Lightroom Classic: Macbook Pro M1

@cletus_lee I run LR on an M1 with 8gb/256GB ssd. No problem especially with the new M1 processor.

On my old MacBook Pro I had 8gb memory and 450gb ssd so I'm really hoping its not that. Photoshop is running absolutely fine btw.

I have a new M1 16 Gb RAM and 2 TB of storage.  It runs fine. A 256 SSD and 8 FB of RAM is probably not adequate. Could this be your problem?

Thanks Jeff, I have just uninstalled Lightroom and I am downloading a fresh install, which I won't try to open until I know that all the system updates are done.

And check again when that finishes to make sure it's up to 11.5.1 - the minor rev might follow the major one.

Then I would download LrC 10.3 again from Adobe Creative Cloud. That has a native version which is much more efficient than running 10.2 or earlier, which was Intel only. It does work but you are better off with the native one.

Hi Jeff, again thanks for the reply, that is incredibly annoying! I just checked and I do have an update available for Big Sur, I done a system update when I got the new computer, didn't think to check if there was any more available. Just downloading it now. Will let you know what happens.

I run on LrC 10.3 on an M1 Mac Mini.

Make sure you update the OS to 11.5.1 which is the current version.

*Marc Feldesman hi Marc, thanks for the reply, yes it’s the newest version of Lightroom classic desktop, operating system is big sir 11.2.2. Previously I was running classic 9.4 on high Sierra 10.13.16

Are you running the current version of Lightroom Classic CC?  What OS were you running on your 2011 MacBook Pro?  There are two potential issues here.  First, if you were running any Mac operating system at or before Mojave, those are the only ones that support 32 bit software.  Starting with Catalina, no 32 bit software runs on a Mac.  Second, if you are running pre-subscription Lightroom (LR 6, for example), it is 32 bit software that won’t run on the decidedly 64 bit Big Sur installed on your M1.
