Everytime I try to open Promise Utility on my iMac (10.13.6) the top menu bar appears showing that the program has launched but I can't get the program window to appear. Does anyone know what the solution might be? I've already tried reinstalling Promise Utility. I'm using a Pegasus2 r6. Thanks.

Hi Jordan,

Could you let us know the current version of Promise utility running in your iMac?

It's version 4.02.0000.17 - I believe it's the most recent version because I just reinstalled it

Hi Jordan,

Yes, 4.02.0000.17 is the latest version of Promise utility.I think it's OS compatible issue making not launching the latest version. Kindly try with installing the 4.02.0000.12 version of Promise Utility using below link:

Ola my friends,

I tried these simple steps and Its working now:

- Please move the promise utility to trash, and empty the trash. 

- Then download the latest promise utility software

- Once after installing the promise utility, Restart the unit and the mac, first turn off mac and then turn off the pegasus wait for 2 minutes and then turn on the mac and wait until it is fully booted then turn on the pegasus and wait for 2 to 3 minutes and then try to launch the utility, see if it works.

- Working fine for me now.
