Note.you can watch the progress the same way, but the display will only show it as backup. Hold down the Shift key on your Mac while you click on the Time Machine "clock" icon at the top of the screen The process for a backup file of about 200 GB will usually take about 7-10 minutes before a message appears on the screen that the process was successful. Note.you can watch the progress of the Verification process by clicking on Open Time Machine Preferences. Hold down the Option key on your Mac while you click on the Time Machine "clock" icon at the top of the screen I really would welcome any advice, I don't want to loose my backups again.Ĭheck to make sure that you are not running any kind of anti-virus application on your Mac, or any other utility that claims to "optimize", "clean", "speed up", etc your Mac.ĭoes the Verification process also hang up when you. I have looked in Console, but I am not sure what I am looking for there is only one error showing there, but googling it, it doesn't seem to be related the error message is " - Unknown CGXDisplayDevice: 0x41dc9d00" and repeats even when no backup is underway. I am using a 2011 iMac, with High Sierra and a gigabite ethernet network connected via an Airport Extreme to the Airport Time Capsule."įollowing that post and responses received, I attempted to run Disc First Aid, but this just froze and I ended up reformating the drive and starting again with Time Machine backups.Īll has gone well until this week, when once again the verification is stopping at 74%, exactly as before. Is there a way of finding out what is happening and if there is an issue with the backups? I really don't want to delete the backup files and start again if I don't have to as I have backups going back a couple of years. I have left it verifying for upto a week, but once it is stuck it never moves on until I skip verification and then it will work okay for a few times.

However, it regularly stops during verification and always at 74%. My Time Machine backups seem to be working correctly, in that it runs backups and I can enter time machine to see files in the backup. I posted the following question in December last year.
