I’m on an M1 Max MacBook pro as well.
The Pegasus1 is now EOL. I get a hard crash when I use the promise utility with a Pegasus1 or Pegasus2. But as long as I stay out of the utility, I can use Pegasus 1 and 2 drives. If you have a newer pegasus you should be fine.
They have a whole procedure for getting their driver to load.
Here’s a PDF to get started… https://www.newtech.co.jp/wp-content/uploads/product-s/mac_supported/20201209_Promise_Pegasus_Driver_Installation_Guide_on_M1_Mac_v1.pdf
IMO they’re playing a little fast and loose with EOLing people’s vital storage without an upgrade path.
The current Pegasus utility does work with an up to date Intel machine. I’d love to go to NAB to give them a piece of my mind.
Are you using the latest Promise Utility? Both of my Pegasus 2 R6s work fine with it for me. I’m with you on Promise’s EOL situation. I bought an Atlas NAS from them, it works, but was EOL in less than a year.
I just loaded it and it says it’s up to date. 4.06…
I check the firmware of my Pegasus2 on my iMacPro and it says the firmware is fine there.
I’m surprised.
I’m pleased to report that after a firmware upgrade my drives are now working on my Mac Studio. Thanks @dcrites for assisting me on this journey via our discord chat
@SamE your firmware might me out of date. I updated my drives with my imacpro and it now reports v5
I’m starting to suspect that My M1 MBPro Max is messed up from too many machine migrations. My firmware’s up to date, but the drives hard crash my machine if I run the utility. Thinking about a clean install.
maybe when you update the firmware using your imacpro will fix the freeze issue. I also had a freeze issue but not again after updating my firmware using my imacpro
I did update the firmware on the iMac Pro. Hard freeze when I run the utility on the M1 MBP.
I had assumed it was an issue with Promise. When I get the time I’ll back up everything I need on my MacBook Pro, do clean install, then copy my files back on.
Flare 2023 doesn’t work on the MBP either. So time to clean up and start over.
Just wanted to thank you guys for the info here - have a 1st gen Promise Pegasus R4 which I’ve been using for 3 years with my 2019 MBP - just got a new M1 MBP and of course it couldn’t see the Pegasus. But the link you provided for changing security settings worked great and I just downloaded the drivers for the current Pegasus line from their site. And despite them saying my RAID is EOL, the new drivers worked a charm and I can now access my Pegasus on the M1 MBP and run the Promise Utility. THANK YOU!!!
