Apple Event: May 7th at 7 am PT
When I restarted my Mac recently, the following message appeared and reappears every time I log in: "Time machine couldn't back up to My Passport for Mac. Files can't be copied onto the backup disk because it is read-only."
I have a 2017 iMac with OSMonterey version 12.3.1.
What can I do to fix this?
iMac 21.5″, macOS 12.3
Is the OWC Mercury Elite Pro a spinning hard disk drive or an SSD? I'm asking because my son-in-law, a long-time Apple user, told me he thought a spinning hard disk drive might be better for use with Mac's Time Machine. He thinks Apple has problems with Time Machine.
The Mercury Elite Pro is an enclosure for HD's. If you buy the MEP that has no drive it in , you can install your own SSD with an adapter.
No app is 100% trouble-free. In 20+ years of Mac US and over 15 years of TM use I have found it pretty reliable. However the the ultra paranoid (I am in that group) like having redundant backups. Why, because a backup drive can fail too! I use TM and also on a 2nd EHD create a bootable clone backup using SuperDuper!. My choice was SD! however a lot of other users prefer Carbon Copy Cloner and love it. Either SD! or CCC will do the job, it's just a personal choice.
Open Disk Utility and run First aid on the Time Machine drive. If any errors appear after running First Aid 2-3 times it is time for a new drive.
What is the best replacement for my old external hard drive (WD My Passport for Mac)?
I have had terrific luck with the OWC Mercury Elite Pro.
Thank you for your prompt responses and suggestions. I appreciate, as you describe it, your inclination to be ultra paranoid when it comes to backups. The MEP sounds good.
