    Cannot upgrade to Monterey with non-apple SSD was this fixed in 12.1?

    Cannot upgrade to Monterey with non-Apple SSD was this fixed in 12.1? There are a lot of us that upgraded the original SSD and don't have the original SSD to reinstall. Was this issue fixed in 12.1? Is there any workaround that works in 12.2? Apple are you also listening?

An older guide (https://forums.macrumors.com/threads/guide-how-to-get-back-old-efi-after-downgrade-from-yosemite.1803934/) said to flash the .scap files using the bless command. The only problem? Any iMac newer than 15,1 only has a .fd...

    Is it possible to update or tweak the USB_A-to-HDMI adapter firmware to make it compatible with a Mac?

    I bought a USB 3.0 (USB-A) to HDMI adapter but was too late to notice it wouldn't work with Mac - Windows only; as such my Mac simply won't recognize my Sony TV. Unfortunately a return is not possible due to the damaged package, so I thought since there's the Device Firmware Update mode which is...
