Seagate not compatible with Mac warning

Thank you and good questions. Haven't experienced any problems with these;

When I look up the internal hard drive within the Mac Studio M1 I cannot get a manufactures name for the 522GB drive.

The external drives in my Lacie NAS drive are both Seagate Iron wolf drives.

Safari browser, I can only say that while using it is when I got the pop up warning

New issue. The first and only time I've seen this

Back in April after transitioning from exFat to Mac, for the external Seagate NAS, I was assisted by an Apple Rep to reformat and have had no issues to date

If this is a one-off to never to repeat again as you indicate— I would simple ignore it.

If it recurs every time you open Safari only, then I would try a different browser and compare your results.

You post no example/screen shot of the warning....? So not much to go on here.

For your third party —

if in doubt search the developers website or contact: Support/Help/FAQ/Known issues/compatibility/Updates

To trouble shoot further you can:

 —SafeBoot How to use safe mode on your Mac - Apple Support

Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache,  etc. 

Login and test. Reboot  as normal and test.  Caches get rebuilt automatically.

In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a  reboot will put it back to normal mode.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

 This will tell you if it a universal issue or isolated to your user/admin account.

Sounds like it might be adware. Download and run the free version of Malwarebytes. It was developed by a long time contributor to these forums and a highly respected member of the computer security community.  If it is adware or malware Malwarebytes should remove it.

I said I thought it might be adware in that there are sudden popups which like adware. It can't hurt to run the free version of Malwarebytes and see what it finds.

If it's not adware that rules it out and you can concentrate on other possible reasons.

Is anyone doing anything about this warning? I got it while using Safari as a pop up and tapped on Learn More now I can't reread it and quite honestly don't know what to do about it. My guess is to call Seagate and ask them what is going on? Just a guess

What is this Seagate... and external Drive?

What does your Safari browser have to do with it?

Old issue, new issue, what changed?

Did you erase/format/initialize the drive? GUID/APFS

What are your thoughts on Clean my Mac system cleaner. I've used it 2 or 3 times, but not since late April 22

Clean my Mac is known to cause issue ! It typically causes as many issue as it is suppose to "clean."

It is not recommended. I would look for an in-app official uninstaller or visit the developers website.
