I'd like to free up space on my mac's internal HD. I currently run with no external HDs.
Seems like one option is to selectively move one or more apps (that I don't use very much), along with their associated libraries, from internal HD to external HD
For the sake of the goals/criteria below, let's say (a) I'm not moving any
/Users/*, and (b)
EHD is an external SSD connected via USB-2.
For any such low-use app
App which is currently wholly-contained on my internal HD, I'd like to know how to move it to
EHD such that:
EHDis mounted/available, then startup or access times for
Appare not a primary concern (slow is ok)
- I'm in control of
EHD's mounting/availability (so if
EHDisn't mounted, it means that I don't care about
- key goals:
- keep macOS on internal HD
- don't move
- regardless of whether or not
EHDis mounted, any operations NOT associated with
App(or its libraries) should have same functionality and performance as they currently do.
I've looked at some old-ish SO questions (Photos.App/Mail.App, IBooks.App) which seem pretty similar to what I'm asking, but I'm looking for more general how-to/best-practice recommendations/gotcha's. I reckon that a naïve approach would be to just drag
EHD/wherever/, but I'm hoping for something less naïve.
For what it's worth, my first target for
App is XCode -- seems to take up alot of disk space, and I don't use it much, but would like freedom to power it up (over possibly painfully-slow USB) when necessary.
