It seems to be a Chicken-or-the-Egg problem: I need APFS to install High Sierra, but I can't format the SSD with APFS from the older MacBookPro Recovery mode, without High Sierra installed. OR that this partition was missing and your notebook went in to Internet Recovery mode which would attempt to download an earlier version.

Interesting in it didn't update as you upgraded to El Capitan. It sounds like the Recovery partition on your Mac is still the one that was created when Lion was installed. Thanks for providing the additional information. I should have noted that I'm using the Disk Utility in Recovery 's stuck in the older version(12.*.*) with no APFS option, and once Recovery begins, it will only download Lion, not any of the more recent OS.Īh, I understand now.

If you don't have those updates that will install High Sierra immediately, then you would probably need to just install Lion first, then upgrade to High Sierra using the Mac App Store.
You should see a spinning globe and a progress bar.
But without the shift it was a more recent version of Disk Utility that could recognize and format APFS.Īre you using Internet Recovery? The proper keystrokes at power on are here. I've tried that once, and it had an earlier version of Disk Utility that didn't recognize APFS. There's another way to load that (shift-option-command-R) that will make available the earliest version of OS X available for your machine. Hold option-command-R at power on for the version that makes the latest version of MacOS/OS X available. WiFi with just a WEP/WPA password should be fine. You would need an internet connection that doesn't require a "splash screen" - such as some types of public WiFi or at a hotel room. With your machine it would require that the firmware be updated, but that is typically done automatically when there are OS updates (since Lion). You wouldn't need to load any earlier version of the OS. If you're going to do this with a fresh install of High Sierra, you should be able to do that with Internet Recovery. However, if you're going to do it, might as well just format in APFS to being with.
At some point (might be the next update) there will be an auto conversion to APFS.

You can format in Mac OS Extended and install High Sierra. I have a SATA SSD and don't have TRIM enabled running High Sierra. You don't really need to do any of that stuff. However, I don't see replacement SSDs for sale anywhere on Apple's web site.can I purchase an Apple-compatible SSD from my local store, to install myself? I am considering attempting to reformat the SSD from my MacBook Air (running High Sierra) via USB cable & Disk Utility, then install High Sierra from the App Store, then physically install back into the MacBook Pro.my question is, at what point would I enable TRIM? After the format, but before the OS install? Or should I wait until the OS is installed?Īlso: Apparently Apple only supports it's own SSDs.due to TRIM compatibility issues. How can I re-format the SSD & enable TRIM, on a machine that only has the OS Lion version of Disk Utility (no support for APFS)? Additionally, apparently I need to enable TRIM on the third-party SSD. I kept taking upgrades, hoping they would fix the problems, but was unable to install High Sierra, without major boot problems.Īfter doing some research, I see that the problem seems to be that I formatted the SSD with an older version of Disk Utility, which doesn't support APFS. Initially, everything went well.but as I upgraded the OS through successive versions, it began behaving strangely.random system freezes, and boot problems. I installed and reformatted the drive using Disk Utility, and downloaded Lion from Recovery Mode.

A few months ago, the hard drive in my 2011 MacBook Pro failed, and I replaced it with an SSD from a well known third party manufacturer.
