Drive Genius For Mac Sierra

Drive Genius is compatible with macOS 10.13 High Sierra. Due to security changes in 10.13, a few things have changed related to the startup drive and APFS. This change is an expansion of the existing System Integrity Protection feature introduced in macOS 10.11 El Capitan, and prevents some features of Drive Genius from functioning as they have.

Hello Wondering if anyone can help please? My old iMac was seeming very slow so I rebooted it, however when it rebooted it wouldn't start up. I got an image of a folder with a question mark, it seems it couldn't find the start up folder. I rebooted in safe mode. When it gets to the point it asks where you want to reboot from there's no picture of an hard drive, it's just vanished! I tried to find the disks that came with it and put the first one in it wouldn't reboot from disk either and now the disk won't eject either.

I've tried a few solutions I've seen online but it seems I can't get past selecting the language because the part to select your hard drive image on the screen is not possible because there isn't one! It seems my iMac has suddenly completely lost its hard drive and seems unable to recognise there is one!!

Any ideas please? Need to ask some questions: 1. What exact iMac model do you have? What exact Mac OS are you using?

Have you ever done an disk cleanup/maintenance/repairs, from a software perspective? By that I mean have you ever run any disk-related software to help with those tasks? There are some excellent products available (both free and commercial) that can help you with that. This is critical: are you making backups to an external device? Mac support for sierra. If yo are, what software are you using for that? How are you making posts here? Adobe illustrator free download.

If it's another Mac, what exact model is it, and what exact Mac OS are you using on that machine? What specific solutions have you tried? If you have a backup, then there are some things that you can try.

But if you don't have a backup, such solutions are somewhat 'risky'. Need to ask some questions: 1. What exact iMac model do you have? What exact Mac OS are you using?
