Hi,

Now that 10.15 is out can we get an update on Pegasus2 Support?

I can log a support ticket if you wish but I'm sure I'm not the only person wanting to know this so I thought it would be better having the official response "in public".

Thanks,

I have the same problem. I just upgraded last Friday. Now it's veteran's day I don't have access to the media we were planning to use with the Family. It's disapointing as you have known about this for 2 months now and have Catalina for one month.

The Release Notes on the download site list Promise Utility version Mac SW 4.04.0000.37 as newly available. However, I can not find it on your site. Also, the Check for Updates function in Promise Utility versoin 4.xxx.21 reports that it is the latest version. Please advise.

Hi David,

There is a utility with support for 10.15 on the downloads page now. It was posted on 11/21/2019.

This filename is R_Promise_Utility_404000037.dmg, it's the utility you are looking for.

You can download it from here rather than the legacy page if you wish.

Thanks for the response. I didn't realize it would be on the Legacy Page of the Downloads Center - the Pegasus2 is also listed on the Current Products page, which confused me. The Pegasus2 R6 is still shown on your website - but is it discontinued (hence the Legacy status?)

I am getting this message when I try to mount Pegasus2 M4 on Catalina MAC OS.

Could not mount “Promise Pegasus”. (com.apple.DiskManagement.disenter error -119930872.)

I already downloaded the utility and installed it.. Any other tips?

The pegasus Utility can see the Device and report on it.

However, I can not see the device on finder and when I try to mount Pegusus2 M4 from the MAC disk utility I get the error listed above.

HELP!!

Happy to report that problem is solved.

2 Steps ..

1. Updated the Pegasus utility to the latest version. I suggest that you update using the utility check for updates menu

2. Updated firmware using the utility check for updates after you update the utility. Reboots system automatically.

3. All Thunderbolt and USB drives are working now

I am using Promise Utility 4.04.0000.39 (C01) on Catalina 10.15.2 on a Mac Pro 2019 with an Apple Thunderbolt 2-> 3 adapter. My setup was working fine on my imac Pro after a driver update. When I moved to the Mac Pro, I can no longer get the Pegasus 2 to be recognized.

Please advise. I have applied the latest driver.

Hello everyone.

I just got a MBP16" with Catalina 10.5.3 MacOS X installed.

I have a Promise J4 and I try Promise Utility 37 and 39 and none of both works. Does not even show the diveces.

I have it using a Thunderbolt 3 to Thunderbolt 2 Adaptor. In System Report I can see it is there and actually recognize other Thunderbolt Units but no the Promise J4 with 4x HDDs 2.5" Drives.

Please provide with a solution ASAP.

Thank you.

Thanks for this post, FYI this works for the older Pegasus as well, it fixed the problem of not being able to run the service report

Hi,

Pegasus2 Utility for Mac 4.04.0000.40 (support macOS 10.13, 10.14)

Is 4.04.0000.40 compatible with 10.15?

I installed it, but Daemon freezes in the background.

Promise Utility 37 and 39 are fine.

Howard Womersley posted this 01 June 2020

It appears that the Pegasus2 R2+ only works with version 4.02.0000.21 of the Promise Utility.

But only version 4.04.0000.40 of the Promise Utility is compatible with Mac OS Catalina (10.15).

I used the 'Check for updates' feature in the utility, updated to version 4.04.0000.40 and it resulted in a system freeze. So, it appears that version 4.04.0000.40 of the Promise Utility is not compatible with Mac OS 10.14.

So, still no Utility for Pegasus2 R2+ and Mac OS Catalina.

***** UPDATED *****

I rate retaurants by the cleanliness of restrooms and the quality of salad ingredients. Similarly, I rate computer hardware companies by their support for the legacy products. Have several Pegasus2 and Pegasus3 devices and am unhappy with the lack of support for "older" devices under MacOS Catalina (10.15). This is not acceptable. I like my Pegasus{2|3} units. However, I feel that Promise does not care about their faithful customers.

This being said, I got both Pegasus2 and Pegasus3 devices working with my new iMac under Catalina. Do not really know what did the trick because I tried several things. Currently, I have both Promise Utility version 4.04.0000.40 (C6) [WWW] and the Promise driver for Pegasus2 [WWW] and Pegasus3 [WWW] installed. I also installed the latest firmware [Pegasus2] [Pegasus3] on all devices. You may want to try just the Promise Utility (4.04.0000.40 (C6)) and update the firmware (you will have to reboot the machine) and see if that does it. I do not want to mess with uninstalling the driver at the moment because the synchronization (LD 0) has been running for over 24 hours on my 64TB Pegasus3 device and it is better if I do not mess with it. However, I will try to make the same work with my 16" MacBook Pro and once I know what the minimum software requirements are, I will post them here.

I hope that Promise finds an idle intern this summer to address the support documentation for current as well as legacy products. This stuff appears to work under Catalina just fine. They just need somebody to check and document it. I know that the marketing side is probably not crazy about that but they must understand that only happy current customers will go out and buy their product again.
