Over the past two weeks, I have noticed the "Available Space" on my hard drive keeps growing, even though I add more files. I have attached two screen shots to show what is happening. I have the 512GB solid state drive on a Retina 15" with the 2.6GHz and 16GB RAM. The formatted capacity is 499.42GB.
The first screen shot shows the HD finder. The left info screen that says "Jeffrey Info" is from the highlighted folder in the finder. The right info screen is of the Macintosh HD and was opened by right clicking the HD on the desktop screen. As you can see at the bottom of the finder box, it also says the my available capacity is 498.03GB, even though you can clearly see that the "Jeffrey" folder is 61.55 GB (plus everything else on the computer). It says I've only used 1.38GB on disk. Considering I have Microsoft Office for Mac Business as well as the full Office Enterprise Edition on Windows 8, Adobe programs, SAP, and other stuff for my work, I've obviously used more than 1.38GB.
The second screen shot is from system information. It clearly shows only 290.58GB available, which sounds correct based on what I know to be on the HD.
The only thing I have changed in the last month is the use of Time Machine. I got this computer in late November and received an Apple Time Capsule 2TB for Christmas. I started using it within a few days of Christmas. I first noticed the incorrect capacities approximately 2 weeks ago, and it has been progressively getting worse.
This is not my first Apple computer. I have been using them since the Powerbook G4 days on OS X 10.2. I am also running Parallels on here with Windows 8 Pro. That has been installed and operating since November, so I don't believe it is related to this issue. I suspect this might have something to do with Time Machine since it seems to have started around that time.
Is it normal for Time Machine to constantly backup 30-40GB/day, even though less than 500MB changed during the course of 24 hours?
Does anyone know why this is happening and how to fix it?
Thank you in advance for any information!
