Bug with MacOS and OSTC3

Otto,

Could you please re-download the Subsurface-4.8.0.dmg from our website? I replaced the DMG with a new one that does indeed include the correct libdivecomputer version that has the fix for this bug.

Sorry about the inconvenience (and replacing the binary was much quicker than going through the lengthy process of making a new release)

/D
