While that may sound a little ominous, there’s no reason to panic. Restoring your Mac OS is pretty simple even for those who have limited computer troubleshooting knowledge.
Before you attempt any upgrades to your operating system or any software in general, backup all your files. Some OS restoring techniques will delete your hard drive. To learn more about backing up your Mac, go here .
What’s even better is there are four ways to restore your operating system, so there are always backup options in case one didn’t work. These options include restoring your OS from the Mac App Store, restoring it through macOS Recovery, restoring it via Internet Recovery Mode, and lastly, hooking up your machine to an external drive with a bootable version of your Mac OS.
Restore from Mac App Store
To restore from the Mac App Store:
1. Click on the Apple icon in the upper left corner of your screen.
2. Open the App Store.
3. Click on the Purchased tab in the Mac App Store window.
4. Look for your operating system from the list of purchased apps.
5. Click Download (you won’t be charged for reinstalling apps).
6. Click Continue to confirm that you want to install software that is already on your computer.
7. After the OS has been downloaded, click Install.
8. Wait for the installation to finish.
Start up from macOS Recovery
If you encountered issues downloading the Mac OS from the App Store, you can restore your operating system through macOS Recovery. This will allow you to choose which versions of macOS you want to install on your Mac.*
When initializing macOS Recovery, the following key combinations will allow you to install different macOS versions:
● Command-R restores the latest macOS that was installed on your Mac without upgrading to a later version.
● Option-Command-R upgrades to the latest macOS that is compatible with your Mac.
● Shift-Option-Command-R restores the macOS that came with your Mac or the version closest to it that is still available.
To initiate the restoration via the macOS Recovery
1. Start or restart your Mac.
2. Hold down any of the key combinations presented above.
3. Release the keys once you see the Apple logo or a spinning color wheel.
4. Wait for the macOS Utilities window to appear.
5. Continue to the next section and choose whether to erase your startup disk or begin reinstalling macOS.
Erase Startup Disk or Reinstall OS?
Erasing your startup disk prior to restoring your Mac OS is up to you, however, you might want to do this if: Buick intellilink firmware update.
1. Your computer is having an issue that Disk Utility can’t repair.
2. The macOS installer says that it can’t install on your computer or volume.
3. Your startup disk can’t be used to start your computer (this is likely to happen if you try to install an older macOS on top of a newer macOS).
REMEMBER, ONLY DO THIS IF YOU HAVE BACKED UP YOUR HARD DRIVE FIRST!
If you need to erase your startup disk,
1. Select Disk Utility from the utilities window of macOS Recovery.
2. Click Continue.
3. Select your startup disk in the sidebar of Disk Utility.
4. Make sure you select the disk name and not the volume name under it.
5. Click the Erase button or tab.
6. If you don’t see an erase button or tab, select the volume name under the disk name, then look again.
7. Complete these fields:
Name: Enter a name for your disk, such as “Macintosh HD”.
Format: Choose Mac OS Extended (Journaled).
Scheme (if available): Choose GUID Partition Map.
8. Click Erase to begin erasing your disk.
9. Once you’re done, quit Disk Utility to return to the utilities window.
10. You’re now ready to restore your macOS.
Restore your macOS
If you’re done erasing your startup disk or you think it’s not necessary, you may proceed with restoring your macOS.**
1. Choose Reinstall macOS (or Reinstall OS X) from the utilities window.
2. Click Continue, then follow the onscreen instructions.
3. Select a startup disk.
4. Click Install.
5. Provide your Apple ID to verify eligibility to install macOS if asked.
6. Wait for the installation to finish.
7. After the installation is finished, your Mac will restart.
Notes:
* If you’re selling or giving away a Mac running on OS X El Capitan or earlier, use Option-Command-R to make sure that your Apple ID will not be associated with the installation.
**If you erased your disk before restoring your OS, or you’re creating a new startup disk, your Mac will direct you to a setup assistant after restarting. If you’re keeping your Mac, you can just use your own information to finish the setup. If you’re selling or giving it away, press Command-Q to quit the setup assistant and finish the process.
Restoring Via Internet Recovery Mode
Sometimes, restoring your Mac OS via Recovery may not be possible – a damaged recovery partition being one of the possible reasons why. This is when Internet Recovery comes in handy.
Available on newer versions of Mac, the Internet Recovery mode is the internet-based counterpart of Recovery mode and works by downloading recovery tools from Apple’s servers into your Mac. Internet Recovery Mode, however, only allows you to restore the OS that came preinstalled on your Mac when you purchased it as opposed to Recovery Mode which allows you to restore the latest version of your OS.
If both of your Mac’s startup volume and its recovery partition are damaged or no longer work, the computer will automatically enter Internet Recovery Mode.
To start Internet Recovery Mode, Part-time champions mac os.
1. Go to the Apple menu.
2. Click Restart or power on your Mac.
3. Hold down the Command – Option – R keys immediately after your Mac starts.
4. Release the keys when the globe appears on the screen.
5. Wait for the Wi-fi menu to appear.
6. When the Wi-Fi menu appears, choose a Wi-fi network to connect to.
7. Once you’re connected to the internet, your Mac will download a recovery system image from Apple’s servers and use it to start the recovery process (note that this can take anywhere between a few minutes to a couple of hours).
8. Wait for the Utilities window to appear.
9. Click Reinstall OS.
Please note that you can only restore your Mac OS on a Wi-fi or Ethernet connection using WPA/WPA2 authentication protocols. If you’re connected to a network using either WEP, WPA-Enterprise, PPPoE protocols or any proxies, you will need to change the network settings to the required configuration first before the recovery process can continue and make sure that it stays that way until the installation is complete.
If for one, reason or another, the Internet Recovery Mode didn’t work as well, you can also restore your Mac OS by using an external drive with a bootable copy of your Mac OS.
Restore Your Mac OS via External Drive (see subject below for instructions on installing macOS on an external drive)
If you install the Mac operating system on an external hard drive, thumb drive, or other storage device, you can use it to restore your OS instead of going through the other three options. https://online-hspls-pay-forum-free-bet-casino-that.peatix.com. Just make sure that your storage device has been properly formatted, preferably as Mac OS Extended, and not FAT, ExFAT, or NTFS.
You also need to confirm that it is using a GUID partition map to make sure that it can be used as a replacement for your startup disk.
To confirm:
1. Connect your external storage device to your Mac.
2. Choose Apple menu.
3. Click About This Mac.
4. Click the System Report button.
Alternatively, you can also:
1. Hold down the Option key.
2. Choose Apple menu.
3. Click System Information.
4. Select Storage from the sidebar.
5. Select storage device from the list of volumes.
Please make sure that the Partition Map Type shown for your storage device is GPT (GUID Partition Table).
Install macOS on Your Storage Device
Follow the same steps when restoring your macOS, but select your external storage device instead when the installer asks you to choose a destination disk.
After installing the operating system on a properly formatted storage device, choose one of these methods to use that device as the startup disk for your Mac.

Use Startup Disk preferences
If you use Startup Disk preferences to select a startup disk, your Mac will always use this disk to start until you choose a different one.
1. Choose Apple menu.
2. System Preferences.
3. Click Startup Disk.
4. Select your startup disk.
5. Restart your Mac.
Use Startup Manager
If you use Startup Manager to select a startup disk, your Mac will start from this disk once, then return to using the default disk.
1. Hold down the Option key after starting your Mac.
2. Release the Option key when you see the Startup Manager window.
3. Select your startup disk, then click the arrow or press Return.
Problem Selecting Startup Disk
If you’re using third-party external devices, your Mac may have some trouble detecting it. Because of security concerns, some of these devices use Option ROM firmware that Mac computers with updated software don’t automatically load.
To fix this, just press Option-Shift-Command-Period at the Startup Manager window. Do this each time you want to start from the external device or from a startup disk connected to it.
If you don’t want to do this and you’re using an older Mac model (2015 and before), you can can disable this security feature and allow your Mac to load Option ROM firmware. Yebo casino no deposit bonus. However, beware that doing this may make your Mac vulnerable to unauthorized access.
To disable this feature,
1. Open the Terminal app in the Utilities folder of your Applications folder.
2. Type sudo nvram enable-legacy-orom-behavior=1, then press Return.
3. To undo this command, enter sudo nvram -d enable-legacy-orom-behavior.
Notes:
1. The amount of time that it will take to start your computer and complete the installation process will largely depend on your external device’s processing capabilities.
2. Should you wish to use an external USB drive as a startup disk, please remember that the drive must have Mac OS X Tiger v10.4.5 or later installed, and your Mac must have an Intel processor.
3. If your Mac is using OS X Lion v10.7.3 or later, you can use Startup Manager to start from your Time Machine backup disk. You can find your Time Machine backup under the name ”EFI Boot.”

The Power Mac G4 is a series of personal computers designed, manufactured, and sold by Apple Computer, Inc. from 1999 to 2004 as part of the Power Macintosh line. Built around the PowerPC G4 series of microprocessors, the Power Mac G4 was marketed by Apple as the first 'personal supercomputers',[1] reaching speeds of 4 to 20 gigaFLOPS. This was the first existing Macintosh product to be officially shortened as 'Mac', and is the last Mac able to boot into classic Mac OS.
The enclosure style introduced with the Power Macintosh G3 (Blue and White) was retained through the entire five-year production run of the Power Mac G4, albeit with significant changes to match Apple's evolving industrial design and to accommodate increasing cooling needs. The G4 and its enclosure were retired with the introduction of the Power Mac G5.

PCI Graphics/AGP Graphics/Gigabit Ethernet[edit]
The original Power Mac G4 was introduced at the Seybold conference in San Francisco on August 31, 1999.[2] There were two variants, officially titled Power Mac G4 (AGP Graphics) with 400 MHz, 450 MHz and 500 MHz configurations available, and Power Mac G4 (PCI Graphics), with 350 MHz and 400 MHz configurations. Colloquially, this generation of Power Mac is referred to as 'Graphite', owing to the colors of the case being similar to the iMac G3 Graphite.
Apple originally planned to ship the 500 MHz configuration in October 1999, but they were forced to postpone this because of poor yield of the CPUs. In response, Apple reduced the clock speed of the processor in each configuration by 50 MHz (making the options 350 MHz, 400 MHz and 450 MHz), which caused some controversy because they did not lower the original prices accordingly.[3]
The early 400 MHz (later 350 MHz) PCI-based version used a motherboard identical to the one used in Power Macintosh G3 (Blue and White) computers including the use of Zero Insertion Force (ZIF) processors sockets[4] (minus the ADB port), in a 'graphite' colored case and with the new MotorolaPowerPC 7400 (G4) CPU. The higher-speed models, code name 'Sawtooth', used a greatly modified motherboard design with AGP 2x graphics (replacing the 66 MHz PCI slot).
The PCI variant was discontinued at the end of 1999.[5]
The machines featured DVD-ROM drives as standard. The 400 MHz and 450 MHz versions had 100 MBZip drives as standard equipment, and as an option on the 350 MHz Sawtooth. This series had a 100 MHzsystem bus and four PC100SDRAM slots for up to 2 GB of RAM (1.5 GB under Mac OS 9). The AGP Power Macs were the first to include an AirPort slot and DVI video port. The computers could house a total of three hard drives, two 128 GB ATA hard drives and up to a single 20GB SCSI hard drive, with the installation of a SCSI card.
The 500 MHz version was reintroduced on February 16, 2000, accompanied by 400 MHz and 450 MHz models. DVD-RAM and Zip drives featured on these later 450 MHz and 500 MHz versions and were an option on the 400 MHz.
The Power Mac G4 (Gigabit Ethernet) model was introduced at Macworld ExpoNew York on July 19, 2000; the new revision included dual-processor 450 MHz and 500 MHz versions, and a low-end single CPU 400 MHz model. It was also the first personal computer to include gigabit Ethernet as standard. Most people saw this revision as a stopgap release, because higher clocked G4s were not available; the G4’s Motorola XPC107 “Grackle” PCI/Memory controller prevented the G4 from hitting speeds higher than 500 MHz.[citation needed] The dual 500 MHz models featured DVD-RAM optical drives. Zip drives were optional on all models. These models also introduced Apple's proprietary Apple Display Connector video port.

Digital Audio/Quicksilver[edit]
A new line with a revamped motherboard but retaining the familiar 'Graphite' case debuted on January 9, 2001. Known officially as the Power Mac G4 (Digital Audio), it is in effect a Quicksilver design inside the Graphite enclosure. Motorola had added a seventh pipeline stage in the new PowerPC G4 design to achieve faster clock frequencies. New features included a fourth PCI slot, a 133 MHz system bus, an improved 4X AGP slot, and a new 'digital audio' Tripath Class T amplifier sound system. The models were offered in 466 MHz, 533 MHz, dual 533 MHz, 667 MHz and 733 MHz configurations, the latter two using a newer PowerPC 7450 processor. The number of RAM slots was reduced to three, accommodating up to 1.5 Gigabytes of PC133SDRAM.
The 733 MHz model was the first Macintosh to include a built-in DVD-R or Apple-branded SuperDrive, the rest of the line became the first Macs to ship with CD-RW drives. This was also the first series of Macs to include an Nvidia graphics card, the GeForce 2MX.
At Macworld ExpoNew York on July 18, 2001, a new line debuted featuring a cosmetically redesigned case known as Quicksilver, and various upgrades to the specifications. It was available in 733 MHz, 867 MHz and dual 800 MHz configurations. The 733 MHz model was notable for not having a level three cache. The SuperDrive was offered on the mid-range 867 MHz model, and UltraATA/100 hard drives were offered on all models. The internal speaker received an upgrade, using a Harman/Kardon speaker.
The Quicksilver line received criticism in MacWorld's review for removing the 'eject' button and the manual eject pinhole, as well as the pass-through monitor power plug, and for the base specification of 128 MB RAM as being insufficient for running Mac OS X.[6]
Updated Quicksilver machines, officially named Power Mac G4 (QuickSilver 2002), were introduced on January 28, 2002, with 800 MHz, 933 MHz and dual 1 GHz configurations. This was the first Mac to reach 1 GHz. Again, the low-end 800 MHz model did not include any level three cache. The graphics in this series were provided by an Nvidia GeForce4 MX400 card. Some of these models have ATA controllers with 48-bit LBA to accommodate hard drives larger than 128 GB.

Mirrored Drive Doors/FW800[edit]
Another generation of Apple Power Mac G4s, officially named 'Mirrored Drive Doors' (MDD), was introduced on August 13, 2002, featuring both a new Xserve-derived DDR motherboard architecture and a new case design. All models were available in dual processor configurations running at 867 MHz, 1 GHz or 1.25 GHz. As with the Xserves, the PowerPC 7455 CPU used does not have a DDR frontside bus, meaning the CPU of the 133MHz frontside bus models could use at most only 50% of the new system's theoretical memory bandwidth, providing no improvement over previous models. The rest was available to the graphics card and I/O systems. A single processor 1.25 GHz model would be the last Power Mac G4 the company offered to the public after the announcement of the new Power Mac G5, introduced in June 2003.
The last real update to the Power Mac G4 line came on January 28, 2003, offering dual 1.42 GHz PowerPC 7455 processors, with features not seen in previous DDR models: a built-in FireWire 800 connector, optional integrated Bluetooth, and optional integrated AirPort Extreme. These were also the first Power Macs that could not boot into Mac OS 9.
With the launch of the Power Mac G5 on June 23, 2003, Apple re-introduced the August 2002 Power Mac G4 because of perceived demand for Mac OS 9 machines. Between that, its low price-tag, and the delayed availability of Power Mac G5s, it proved a strong seller, albeit for a relatively short time. Production stopped on June 27, 2004, and the remaining inventory was liquidated, its discontinuation ending the 20-year legacy of Classic Mac OS support.
