I'm not sure why but ever since I updated on the latest OSX version, my saves are taking a very long time. I have tried a test on a new sequence with one and several effects and it saved quickly. This appears to be an issue with this one sequence. There was no importing of data, it was all made in XL. I've attached a zip file with the files needed for someone to take a look at. Not sure why this is happening and hopefully someone can find a solution for it.
Thanks guys
PS. when I hit save, it will save and continue to "save" for hours and hours. Judging by the "saving" in the lower left corner of the screen. If I close xlights after a few hours of it "saving" it will ask me if I want to save any changes and I hit yes. So at least it is allowing me to save my changes and such. I just can't save more than once without closing xlights.
