简介

Hinweis: Wenn du das neueste MacOS auf einem Apple Computer ab 2009 oder später installieren willst, dann folge stattdessen der Anleitung zur MacOS Internet Recovery.

Wenn du kürzlich die Festplatte vom MacBook oder iMac getauscht oder aufgerüstet hast, musst du Mac OSX neu installieren. Diese Anleitung zeigt dir, wie du OSX High Sierra auf eine leere Festplatte mit Hilfe eines bootfähigen USB-Sticks installieren kannst.

Bevor du beginnst, erstelle einen bootfähigen USB Stick. Du brauchst dazu einen Mac mit High Sierra, um die 7,7 GB große High Sierra Installationsdatei vom App Store zu laden. Du brauchst auch einen leeren USB Stick, auf den 5,4 GB passen.

Folge dieser Anleitung, um einen bootfähigen USB Stick mit macOS High Sierra zu erstellen, bevor du mit der Anleitung fortfährst.

    • Klicke oben im Fenster auf die Schaltfläche Löschen.

    • Wähle einen Namen für dein Laufwerk (du kannst es später umbenennen). Lasse das Format als Mac OS Extended (journaled) und das Schema als GUID Partition Map.

    • Um eine SSD zu verwenden, musst du das Format APFS wählen. Für eine mechanische Festplatte, oder wenn die Festplatte neuere Mac OS-Systeme nicht unterstützt, belasse das Format Mac OS Extended (Journaled).

    • Klicke auf "Löschen". Wenn der Vorgang abgeschlossen ist, klicke auf "Fertig".

    • Beende das Disk Utility, indem du auf das rote X in der linken oberen Ecke des Fensters klickst.

    If, like me, you have already formatted the disk in the Windows operating system, you will probably encounter an error message when trying to select the new disk as the installation destination that warns you that the disk is not "GUID partitioned", and that you should go to erase it with the Disk Utility application.

    The trick here is to go to the DU application, select the "Show all devices" option in the top left drop-down menu and then select the root device for your disk, and not the individual partitions. That is the one that you must delete, and for that root device, the DU application will show you the option to select the “GUID Partition Map” inside the Erase button window.

    Best regards!!

    Even knowing about that and doing it many many times, i still to this day, often look at the ‘volumes’ and try to erase. Not until I see no partition map options do i realize I'm not showing the drives.

    With an SSD you should choose APFS and not Mac OS Extended!

    Arthur Shi -

    If your MacBook Pro isn’t compatible with the new operating systems (Mojave and later) which use APFS, (such as an early 2011 MBPro) then you should use Mac OS Extended Journaled, or else it won’t let install the OS. If you made the mistake of formatting to APFS, then go back into Disk Utility, select your SSD, and go Edit>Delete APFS, and then select the view option to show you all volumes and erase again to Mac Os Extended.

Use disk utilities from the Mac OS installer to format the new drive in a Mac format. Then install the Mac OS. New drive won’t show up in the installer until it’s Mac format.

littleduckltd -

A small pointer for any who have the same issue. I put in an entirely new 2TB WD sata drive and then preformed a fresh install of snow leopard onto it. When I got to the section to choose which drive to install to there was no drive image.

I clicked at the top on disk utility, then picked the drive, clicked erase and erased the drive. THis actually formats it into a mac format. after this I closed disk utility and voila the drive was now visible and installation could commence.

Good luck

This Mac OS X Install Guide is really outdated. When using a Recovery disk to install Mavericks, OS X just told me it couldn't install Mavericks. Didn't tell me why, it just told me it couldn't do it. I did something like this:

1. Get a USB or Firewire HD enclosure. Use the iFixit HD Replacement Guide to put your new HD into your iMac and put your old HD into the enclosure.

2. Plug in the enclosure and its USB or firewire cable to your iMac.

3. Hold down the option key on your keyboard and turn on your iMac. When it boots, it should recognize your old HD in the enclosure and give you the option to boot from that drive. Select that drive. It's just like booting when the drive was still in the iMac but maybe a little slower.

4. Now go to the App Store and Download and install Mavericks. You'll need to select "Show all Disks". You may need to use Disk Utility to format or erase your new HD if it doesn't show up. Use Migration Assistant to transfer apps and data from your old HD to your new HD in the iMAC.

I need help. I have 10.5.8 on my macbook. My hard drive is messed up so I cant erase the hard drive as the erase button is greyed out. So I am trying to format everything in my macbook and reinstall osx. But I got 10.6 only. Please advise how to erase everything on hard disk and installing clean osx on macbook? Is anything I should know?

Ahmd Faruq - 回复

Depending on your MacBook, you may be able to install Mac OS X 10.6 onto that machine. You will need to boot up from that disk prior to doing the erase of the hard drive as well.

After installing new HDD in IMAC...power on gives a yellow screen. Is it possible to get to formatting utility from this point? I tried a command R no luck.

Rich - 回复

I think what's Happening Here is a lot of people aren't formatting drive before hand. Old drive dies new one pop in and your good. This is not the case Mac, Kaspersky uses a tool to allow you to make a bootable disk from your usb for your Mac or your PC. Use the tool that used because there are a lot of viruses out there. That what you want to do since you don't want to rip your Mac apart is download Ubuntu ISO file learning is a bootable ISO you can use FAT32. Once you do that put it in the USB drive boot from the USB. Sorry forgot to stop you need to get rid of your vram clear option RVP or something. Next is booted off the USB having its command option r. Now you want to format Drive using Ubuntu. Yes Ubuntu free where is more powerful that are Mac OS X and it's free. Now you have to remember using a Mac which is a Linux machine and it's grub so the file extension is htls. Grub you do not format NTFS…

Kapsol -

Once you've done that you need to os. So you can pay the $20 for it which is a joke you could download it from a torrent I'd be very careful doing that or if you have a 2011 that came with it manhole command-r now the problem here is it will not allow you to connect. Therefore you need to open your router settings if you have an old router that would be best.

Kapsol -

Set that router up to connect to an open DNS so where it says DNS connection you want to use Google DNS OpenDNS Mike's DNS ect Google DNS in OpenDNS are the best. And then you have to hold command-r and it now will allow you to connect to get the file. Once that gets the file it'll start the installation process your screen will turn white let it turn white holdzkom and wipe out the vram again reboot redo it and your set. And now if you're still having problems do a hardware check I think that's holding the just hold D at start up. Keep hope alive. You guys can donate for all my time put into this BS very awesome even $0.10 a penny anything be better than nothing kapsol101@yahoo is my email and PayPal if you have problems just email me now I'm always here to help. Unless I die like Steve Jobs did cuz karma's a bch.

I have a MacBook Early 2009 A1181 Model. Just ordered a SSD from Amazon, and have all of my stuff backed up on the external hard drive I use for backing up. I still have all of my installation CDs, but want to make sure of the tools I need for this. I know I take the battery out, and that metal cover in that area, but for my Mac I'm not sure if it would be the same tools since it is older than what you guys have.

Also, one quick question, can I change the processor in this? I will be switching out the ram soon, likely after tax season, but I want to get a faster processor if possible.

I replaced the original 320 GB OEM Apple/Hitachi drive in my 2007 iMac with a 3 TB Hitachi/HGST drive today using the iFixit guide. To reinstall OS X, I used an Apple USB thumb drive, which after reformatting with Disk Utility, is currently downloading Lion from Apple. I also decided to run the formatting/reinstallation before reassembling the front bezel and glass, in case my son and I did something wrong in the drive replacement. Fortunately it looks like we did everything right.

Thought that I would add this comment in case someone has similar situation. MBP late 2011 replaced HD with SSD (Samsung 850 EVO). The angle on the install was that my Time Machine and Old HD were encrypted. When encrypted (Time Machine and CCC clone of drive), the Recovery HD is not setup (not sure details, perhaps this is how encryption works). Either way, setting up a bootable Install USB drive (8 gig minimum for Yosemite) was necessary. Sequence was full backup (I did both Time Machine and CCC to be sure)., create bootable USB installer drive (Google it, I used the Disk Utility method). Shut Down, Reboot with Command-R, plug in USB drive, format new disk, load Yosemite from USB to new disk, then shut down, Restart with Command-R, then load Time Machine backup. The clean Yosemite install setup the Recover Partition on new drive and the files copied from Time Machine restored system to original state without messing with newly created Recovery partition. Then encrypt new drive and you are done.

Stephan Gysi - 回复

I have a 2011 MBP17 and its on a third or fourth failed GPU. This time I have an external screen which gets a good signal so there is some sort of output but the main screen is totally non-functional.

I’ve had to replace the disk now too. I have a bootable installer on a USB drive for High Sierra.

The problem is that the installer and Recovery both want to put their windows on the original screen leaving me with a blank grey screen on the external monitor (with a functional pointer). Its clearly acting as an additional monitor as I can move the pointer off the left side of the screen as if there’s more screen space over there.

Is there any sequence of key strokes that I can use to do a fresh install of High Sierra without actually being able to see what I’m doing? Or some magic cheat code I can put in to force it to only consider the external monitor as existing (ie completely ignore the main MBP one)? Such things seem possible from within the OS with normal settings but I’m not at that point just yet.

Bruno Nog - 回复

Added a slight twist to the install - instead of High Sierra, I had to go with El Capitan. This may be validating a recommendation I found to go with the OS version that came with the iMac when purchased. Still tried High Sierra first but the bootable USB created for High Sierra was detected by the iMac (24 inch mid 2009 model). The install did not even start and I got the stop sign. Tried to create a boot USB this time for Sierra, no luck there, got the “/Volumes/MyVolume is not a valid volume mount point” message numerous times. I suspect the Sierra download was at fault, although a valid Apple file. Anyways, went back to El Capitan, boot USB ok, install started and got a valid screen for the first time with the new SSD. Formatted the SSD and the install completed like a charm.

Hello,

I will follow your tuto to install high serria on my macbook late 2009.

I bought an SSD, and i will replace my old HDD by the SSD and will install high sierra on it.

My question is before to install high sierra, I will format the SSD, and in this tuto you request to use the format Mac OS extended, and when I search on the net, many time I found that is preferable to format the SSD in APFS ?

Could you confirm me that I have to us Mac OS extended instead of APFS ?

yes, it’s maybe possible, but not recommended, because the hardware optimisation is maybe not present in this lower OS version, so the OS work, but there are a risk of bug
