Can someone tell me how to switch back to previous OS on Macbook Air M1?
Tahoe has slowed everything on my computer. Maybe my system is too old for it.
I would like to return to previous OS.
Is that possible?
MacBook Air 13″, macOS 26.2
Downgrading to an earlier macOS version is not a task to be taken lightly. It's easier and wiser to work through any problems you are experiencing than trying to downgrade macOS.
Before you attempt to downgrade your Mac, you must first cross your fingers, kiss the St. Christopher and hope all goes well on your journey backward.
Downgrading requires that you format the drive to erase all the data on the Mac, reinstall the older OS and finally restore your files from a backup made prior to the installation of the newer OS. Additionally, the Mac’s firmware may also have been updated when the newer OS was installed, potentially requiring you to Revive or restore your Mac in DFU mode. using a second Mac.
If all that sounds complicated and risky, you understand the reality.
1) Backup your files to an external disk with Carbon Copy Cloner or SuperDuper!
2) Download the older macOS version and create a bootable USB installer for it on a USB flash drive. This is insurance in case the Mac can’t/won’t boot in recovery mode.
3) Start up your Mac in macOS recovery mode.
4) Restore items backed up with Time Machine on your Mac from the backup made before your upgrade to Tahoe, or restore your files from the CCC or SuperDuper! backup you made before you started the downgrade.
