Why 2 HD icons on desktop?

[bplein]

I hope this shows all three drives.

The first one, I truly believe, is a nonsense APFS volume. Note that it has no data, and it's actually mounted on "/Volumes/Macintosh HD 1" while the other two are mounted as expected.

Here are my mounts from a Catalina system (not my iMac Pro) (I've removed my other external drives and system mounts)

/dev/disk2s5 on / (apfs, local, read-only, journaled)
/dev/disk2s1 on /System/Volumes/Data (apfs, local, journaled, nobrowse)

In your case, disk2s1 is mounted as an empty drive, and the other two are mounted just like mine above.

If you trust me, and have a backup, delete that first one (disk2s1 in your case, mounted on "/Volumes/Macintosh HD 1") and then reboot and they will renumber and you'll be back to normal. You can also rename the - Data - Data to just "Macintosh HD - Data" and it will continue to work correctly.

Ok, Sounds like you dodged a bullet. So you have Macintosh and Macintosh-Data appearing? All I care about is you are OK?

Again, I never had a problem. Both appear in Disk Utility but only one appears on the desktop.

Good glad to hear it. Apple is very forgiving, it can be a simple fix or be a nightmare, far easier than Windows. Glad everything is going good.

This ain’t my first rodeo. I’ve been hacking on Macs since they started using Intel (well I also had an Apple ][ when they were new and a Macintosh first gen when they were new).

I use dd all the time and am quite comfortable in the command line. I was creating my own DIY fusion drives and in fact that’s what I have in my Mac mini server ... 512GB SSD and 1TB HDD.

Bill,

I didn't realize you had a quite a background. I taught myself computers after having years of Windows, (which I hated) until 2014 when an inquired new MacBook Pro, a realized how easy it was to master. Now I have a new 27" iMac I bought a couple of months ago. I apologize for thinking you needed help. I wish the best for you, and will talk to you soon.

No worries, I do like people who are willing to help. That's the best part of MacRumors (and the worst are those who don't help and just cause issues LOL)

Are you replying to me or the OP?

Sorry if I quoted the wrong poster. It was intended for the OP.

I never understand why people say they hate any OS. In 2020 Windows 10 is great, there are also some very good Linux distros and MacOS is also great. Just because I own a Mac doesn't mean I can't appreciate other products.

But I can still hate on Windows

macOS isn't perfect. In fact Apple is making its advantages fewer by the day. Remember when software updates were small and quick?

But it's illogical to hate something that does a good job and looks quite attractive into the bargain.

And major updates weren't free 🤪

My son and a Windows 8.1 and upgraded to Windows 10 when it was offered. The problem with Windows 10, it probably would work on fast PCs with bags of RAM. Not a 2.1 processor with 8 gigs. It just too bloated. Just my opinion. Windows XP and 7 were my favorite before I went to Mac.

Windows 10 runs better on really low spec ancient computers than anything which preceded it.

Attractive is subjective. I dislike the Windows interface. I don’t like PowerShell. Until they added a Linux subsystem it was just a bad environment for working with remote Linux/Unix systems. I prefer UN*X.

(gasp)... blasphemy! 😂

Yeah, Windows has come a long way. I don’t think it’s great, but is sure is vastly improved and still improvin.

I have a friend who used to be Mac, then was always trying to use Linux on the desktop as he’s a developer who writes a lot of code for Linux. He’s now with Windows as the the WSL2 integration is supposed to be really good.
