Hi peeps. I know there are similar threads, so please don't blast me. One thing I have learned since receiving my new 27 iMac (love it!), is that it's easy to lose your mouse pointer on so much real estate. I've used a few of my personal pictures as the background (which look awesome), but there isn't enough contrast with the pointer..and my eyes aren't the best. I saw that there are some background applications in the App Store, and I know there are sites that have apps. I would just like some input into your favorite places to get backgrounds. On my iPhone and iPad I like to change my lock screen backgrounds every week or so just to keep it fresh. Thanks for your input!!
