Apple is about to release updates to their line of Macs: iMacs, MacBooks, etc. Here are some reasons to wait to buy if you’re in the market:

1) Apple tends not to produce enough supply for demand.  This helps their stocks, but not their fans.  Once production of the new line is in full swing, last year’s models will be discounted…
2) Also, Apple tends to need patches for programming issues on new models. I’d wait til the first patch is released.  By then all the wrinkles should be ironed out.  

3) Rumors abound that 2017’s updates will be even bigger.  Apple probably waited on their best updates because of Samsung’s recent problems.  Why put out an Ace when your competitors have dropped a deuce?
