… 10.9.5.
1) put new SSD in external enclosure connect to mbp and use disk util to format to Mac OS Extended (Journaled)
2) still in disk util use the "restore" tab and select the current HDD as the source and the new SSD as target.
3) install new SSD in mbp, boot normally.
This should give me an exact clone of the current HDD onto the new SSD correct? …
Disk Utility 13 (517) in OS X 10.9.5 here allows me to select (drop) as a source a partition but not its disk.
If you find the same limitation, and if you use the OS X startup as the source for restore, then there'll be no Recovery OS on the destination – but I shouldn't worry about that; (in case of emergency) you have another computer and (before too long) there'll be installation of Yosemite.
