I ran into a problem where one of my 256GB MacBook pro ran out disk space. It turned out the problem was caused by a run away Mac OS/X photo library. I had two photo libraries on the Mac totaling about 200GB (sizes shown in Finder, may not be actual sizes)!

First problem I found was the conversion of iPhoto library to Photos library left behind a 73GB file in /Macintosh HD/user/me/Pictures/. The solution was simple – delete the old photo library. I did not recover a full 73GB after I deleted the file, I got back 10-20GB according to Mac system storage page.

The second problem was new photo library /Macintosh HD/user/me/Pictures/Photos Library.photolibrary had a size of over 120GB. It was way too big for the 30k+ photos I had on the Mac. I did a bunch of clean up hoping that they would shrink the photo library. But to my dismay, the photo library only reduced by about 10%. The steps I took to do the cleanups are:

Export photos that I did not need on the Mac to an external drive. It took only seconds to export thousands of photos. The steps are:
- Connect a USB hard disk to a Mac
- Open Photos
- Select File Export Export Unmodified Original for 10 Photos…
- Select a location in the USB hard disk
Delete photos that I had exported
Delete photos in Recently Deleted folder in Photos
Run repair on photo library to make sure photo library is problem free. This takes a couple of minutes on a fast MacBook. The steps are:
- Hold down <Command> + <Option> when opening Photos
- Select Repair

I spent hours searching the Internet and Apple forum hoping someone had encountered the same problem before me and found a solution. No luck! I also posted a question on Apple forum but did not get any response. May be I was the only one that had come across this problem.

I can compile and run my OpenGL application. I found that if you drag the app window (I'm not using full screen) then the animation starts to show. Opengl. However I had to change my Framework Search Paths to include:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworkswhere OpenGL and GLUT framework + headers are now placed as I couldn't find any OpenGL/GLUT headers in the old search path System/Library/Frameworks (although the framework was still there, no headers were included). I also had to make sure my includes were GLUT/glut.h instead of just glut.h.This gives me new warning messages in form of:default Unable to load Info.plist exceptions (eGPUOverrides)' and 'saved enable noise cancellation setting is the same as the default (=1)I haven't checked them yet, and what their implications are.What really bugs me is what Esenthel says, that there is just a black screen after compiling and running the app.

I noticed on other Macs that photo libraries grew and shrink when I added or deleted photos, but not the photo library on this MacBook Pro. Older version of Apple photo apps iPhoto or Aperture had functions to compact a photo library, however I cannot find the same feature in the new Photos app.

I was pissed! I decided to find a solution myself. Here is what I did:

Export all photos in photo library to a USB hard disk (same as above)
Delete photo library /Macintosh HD/user/me/Pictures/Photos Library.photolibrary on my Mac (I did this in Finder)
Create a new photo library. The steps are:
- Hold down <Option> when opening Photos
- Select Create New…
Import photos I just exported. The steps are:
- Open Photos
- Select File Import…

After all the agony, my photo library is less than 17GB.

Hope this helps!

Squash is a lightweight, dead-simple image compressor. If you’ve got .jpg or .png image files that are too big to send or that are taking up too much room, this is the app for you. Its drag-and-drop interface makes it easy to compress pictures one at a time, or in batches.

Plus, you can adjust its output settings with just a few clicks. Need some organizational help while you’re at it? Use the app’s built-in file renamer to bring some order to your image library. Here’s how to start Squashing.

How to reduce size of pictures in just two clicks

To start using the app, just drag a .jpg or .png image file onto the big clamp in the app window. As soon as you drop it, your image will be squashed. Squash will let you know how much the file size was reduced by (or if it was Unsquashable).

If you want to keep the compressed version of the image just click the large button marked Save Image and select a destination. You can do this with individual images, or drag a group of files and compress them at the same time.

Customize image compression settings

You can specify the image compression rate, change the storage format, or remove JPG data to reduce image size.

Click the “gear” icon in the bottom-left corner to adjust your compression settings.
You can choose whether you’d like to save your squashed files as .png, convert your .png files to .jpg, or remove .jpg metadata for more compression.
Use the slider bar to select how much you’d like to compress your images: lower image quality means more compression and a smaller final file size.

Renaming and reorganizing

If you need help organizing your images, the app’s file renamer has you covered. It automatically adds a suffix to the name of every squashed file, making them easy to separate and sort.

To set up this function, click the “gear” icon and enter a suffix in the designated field. You can also designate a folder for all your squashed files to appear in — just use the drop-down menu marked “Automatically save files to…”
