Then, double-click it and install onto your target external drive. If you don't move it, it will self-delete after installation, and you want to archive it for future use. I cover my top performance tips and recommendations to help you if Lightroom Classic is running slow. After it downloads and launches, quit the installation and move the installer from the Applications folder to another location. For an extra 100 the OP could get the base Mac Studio M1 Max (10-core CPU, 24-core GPU, 32GB memory and 512GB SSD). Since the app requires a significant portion of your devices memory, opening. So, the price for M2 Pro plus 1TB SSD would be 1899. Make Sure Youre Running the Latest Version of Lightroom 2. You get the macOS installer from the App Store app. For example, 32GB is only available if the OP steps up to the base M2 Pro version (10-core CPU and 16-core GPU). If you're running Lightroom or other photo app that maintains a database, put the catalog/database on the new external for faster performance. You can put it in a $10 USB 3 2.5' enclosure. Not as fast as an SSD, but boot and launch times are 90% of the way there and a huge improvement over a standard HD. I've seen deals lately for a Seagate 2.5' Firecuda 2TB drive for $60. As for drives, a cheap but adequate option with more storage is a hybrid drive. Running macOS from a USB 2 drive will be painfully slow. If you’re running any anti-virus or anti-malware software, try temporarily disabling it and see if Lightroom Classic runs at a normal speed. One question, Where should I be able to find a downloadable copy of OS and should I get the ISO or dmg for the easiest install? Also, if I upgrade my ram to 16gb (pre-retina macbook), what is a good source for quality ram? Thanks! I'm thinking of getting a Seagate 500gb or 1TB SSD to run it off of. Thanks for the input! I'm definitely going to go the route of getting an external drive and run Mojave or High Sierra off of that.
