![]() ![]() Updating to macOS Monterey with an Aftermarket SSD OWC support suggests same workaround (reinstall Apple SSD, install Monterey, reinstall OWC SSD, install Monterey) I updated to Monterey by swapping the drive to original Apple SSD and update to Monterey, swap to Sabrent SSD with adapter and update to Monterey again. I had almost 0 crashes during Big Sur, but now I get 3 to 4 crashes a day, very frustrating. My Mid 2015 15" MBP with 1TB Sabrent SSD (Sintech adapter) started to crash a lot after upgrading to Monterey. Xaphier and others have reported frequent crashes after installing Monterey on a third-party SSD: Upon successful completion, reenable SIP ( csrutil enable in macOS Recovery) Sudo bless -mount / -firmware /path/to/your/extracted/fd/or/scap -verbose -recoveryįollowing successful execution, shut down Mac then turn it back on to begin fimware update process (the Mac may reboot several times) scap file which corresponds to your Mac's model identifier (as reported in "System Information.app") from "/Volumes/Shared Support/com_apple_MobileAsset_MacSoftwareUpdate/ 40charstring.zip/AssetData/boot/EFI/EFIPayloads/" Mount "Install macOS Monterey.app/Contents/SharedSupport/SharedSupport.dmg" (if you receive a "Resource busy" error, it may already be mounted)Įxtract the. As long as you have the firmware file (can be extracted from BigSur/Monterey installer itself)įor those without access to an Apple SSD, a possible workaround is described separately by u/lbableck and 传说中的慕容, though it requires firmware version ≥195.0.0.0.0 already be installed (check "System Firmware Version" (≥macOS 11) or "Boot ROM Version" (≤macOS 10.15) in the Hardware section of "/Applications/Utilities/System Information.app"):ĭisable SIP ( csrutil disable in macOS Recovery) If you already in 195.xxx BootRom, you can manually upgrade your firmware through terminal as well. ![]() Key is, all those units already on BigSur firmware version (4xx.xxx) I do several Monterey upgrade on my customer's macbook which already have my custom branded 3rd party ssd inside, and all installed just fine. Regardless what SSD is installed in your Macbook. You should have no problem installing Monterey if your BootRom version is already on 4xx.xxx digit. Installing Catalina or BigSur first won't help, since it won't update your firmware either. So, something like 122.xxx, 162.xxx, or something older like MBA.xxx & MBP.xxxx, you won't be able to update to Monterey right away, because the firmware wont't allow new version installation on 3rd party ssd. Prior to that, you can't update firmware using third party, only through original apple ssd. If you already changed your ssd back in early mojave or high sierra time, you firmware was not updated since that time, because, only after 195.xxx BootRom version (which came together with Catalina 10.15.7) Apple enable firmware upgrade through third party ssd. Maleficent_Stranger's reddit comment, the bulk of which is reproduced here verbatim, offers more detail: Reports of having to install an intermediate version like Catalina or Big Sur beforehand appear to be incorrect, at least in this case. The new firmware showed the correct version, 428.40.10.0.0.
