Good afternoon - I have a few questions for only those that owned both Mac and PC with extensive use on Adobe products mainly Lightroom and Photoshop. With much research I am still concerned about making a switch from my current PC to the Mac. I used to view Mac as superior quality, however I have heard some bugs with the new OS (not that MS has never had that). My main concern is the fact the Apple is using the Radeon which I hear is less powerful the Nvidia, especially when used with Lightroom. My third concern is the inability to swap out hardware if ever needed and paying a tech to do so. Do those the have had both - How do you feel the LR performance is when compared to the two systems? Are there any other concerns or non-concerns that I should not before making the plunge. I love photography (not professional) and I do not want to regret my decision.
