Need good live contact for RIM Blackberry to get help removing 3rd party software. Apple says it can't help me.
I have RIM from Blackberry on my iMac probably from an earlier computer. My external DVD/CD player won't work and Apple Support tells me it is because of this old BB RIM software and that Apple cannot remove it. I have not had a Blackberry since 2011. I have banged on Blackberry by phone and online to no avail. Please help me find the right contact at Blackberry to get this off my iMac. My external DVD/CD player won't work.
iMac 27″, macOS 10.15
