I have a Macbook Pro 2013 (2.6GHz Dual Core Intel Core i5, 8GB 1600 MHz DDR3 and Intel HD Graphics 4000 1536 MB Graphics card) It is still going strong with no slow downs. I dont want to upgrade just because its now outdated as it still performs what I require of it. What is happening now is that I cant update the OS or even download any new apps from the Apple Store. Is there any alternate solution to this?
