Hi, I just discovered that I'm running on Sandbox since a week -- unexpectedly
I had done a "backup" to Sandbox and told the program to then, after finishing, to restart from Sandbox because I wanted to quickly check upon a new program installation which would involve running a complex installer.
I thought that this change of Startup Disk would be temporary -- similar to a choice of start volume when you hold the option key upon startup.
Since the Sandbox concept is such, that you use the Sandbox system in a temporary manner anyways, I suggest to let this change in startup volume also be just *temporary*.
Sincerely, martin.
