Anyone trying to install a RocketRAID 2710 in a Mac will be unsuccessful.
Of course, if they correct this issue, then it may work in later versions of the driver. The most current driver at the time I was having this issue is / was:
(I have already reported this issue and my findings to Highpoint.)
The reason is the PNPID is missing from the OS X .PKG files.
This is a flaw in the OS X drivers / package that needs to be corrected. The missing PNPID / IOPCIPrimaryMatch String needed to be added to the info.plist to correct this issue is as follows:
I was able to get my card finally recognized and working in my Hac by making this correction. I have attached my corrected file here, and it was installed on my x64 Lion 10.7.2 Hac and now works perfectly. So I don't know if my attached file will work on your system if you are running 32-bit or Snow Leopard (or earlier).
What I did was install the RR272x_1x-Mac-v140_111018 version of the driver. Then when the install finished, at the "Restart" window, I went into /System/Library/Extensions and copied the rr2722.kext to my Desktop, edited the info.plist in the rr2722.kext to add the above ID, Trashed the rr2722.kext in /S/L/E/, copied the now edited rr2722.kext to /S/L/E/, then I used MyFix 1.3 to deal with caches, ran Repair Permissions, THEN I clicked the Restart button and on reboot, worked perfectly.
Post here if this worked for you so others will know.
