So I finally bit the bullet and upgraded from my 2010 MBPro that was running Mavericks happily. I only upgraded as I felt the age of the machine was getting on & I wanted the bigger screen. So I purchased the MBPr with 15 inch screen 2 months ago. I am sad to say I am kind of disappointed in it. 1) Safari constantly seems to not to want to go to web pages and I spent a lot of time looking at a beach ball (Chrome seems to work more efficiently, but I prefer Safari) - you go to search things and you just get blank pages and that is IF it even will do a search to start with, I find I have to close Safari and open it again and may have to do that a few times before it will work. 2) Force Touch drives me nuts - just too sensitive and I am sick of scrolling pages to find it highlights them instead and I have even turned off Force Touch. It was so bad I even took it to Apple and they checked the diagnostics on it and it came up OK. I have not bogged this machine down, it is 3/4 empty still - and I don't keep video on it, only iTunes and not even many photos as I keep them all on External HDs. And even with my new iPhone 6S (brought at the same time) I have issues with Safari & when I sync iTunes I suddenly seem to have 4GB of "data and storage" taken up and yet I don't even have any video or documents on there, and all things such as key note, iMovie and such are not even installed on it - but this has suddenly appeared when I sync??????? I don't keep emails (delete them straight away after reading & also the delete box is empty) and I keep minimal photos on there. I just find this is getting so frustrating and for the first time in many years, I am suddenly feeling like Apple is becoming more like a lemon?????? I love Apple products and always supported them, but suddenly I feel they are not worth the hassel? Am I the only one???????
