The last couple of months upgrades were needed to run the latest version of Mac OS X (“Mavericks”) and the latest Xcode (5.0). This seemed to stress my 2007 MacBook Pro. Problems included computer not booting, fan suddenly revving full speed nonstop and shutting down the computer, tending to overheat, and occasional other weird behavior. With various internet-search aided troubleshooting, problems were “solved” (for now?). Then suddenly (it seemed) the hard disk was full, and I had to work at freeing up a lot of disk space…supposedly should have at least 15 GB free…Omnidisksweeper (a free program) was a major help to accomplish this, and I should run it periodically. So the MacBook seems to have settled down fairly well, though I probably should get a new one next year.
Xcode 5, needed for programming for iPads and iPhones using iOS 7, has been less problematic. It’s actually a big improvement, with some things being much easier. Like “autolayout” and “code signing.”
Next came HeartCharts 2.0. I just submitted it to the App Store today. I hope it gets out before Christmas, but might not, since Apple is closing the review process for a week. 2.0 looks a little different because of iOS 7 (which is required), but not much. I added chart for myocardial ischemia and infarction, and an image for clot in the left atrial appendage, as well as some aids for navigation. Next blog post will come after this version is approved and available! At that time I will also update the page describing HeartCharts.
