Short story: if you try to do *any* iPhone development with a 1st\/2nd\/3rd gen Pro or Air right now, you may screw-up your laptop – massive overheating. I did. My Air is now almost unusable – thanks, Apple!<\/p>\n

Apple is currently:<\/p>\n

    \n
  1. Forcing all iOS developers to use Xcode 4, even though it only went live 1 week ago\n
  2. Forcing all Xcode 4 users to run OS X 10.6.6., even though it only went live a couple of months ago\n
  3. …and 10.6.6 appears to have an overheating bug\n<\/ol>\n

    For me, I installed the 10.6.6 update, and immediately my laptop went into massive overheat. Nothing brings the temperature down. Multiple processes are being run on high (up to 100%) CPU that normally do not show up, the load factor is enormous. CPU temperature over 80 celsius, with nothing but a single firefox window open. Sigh.<\/p>\n

    I believe this is a bug with the much-praised “make OS X use your dual-core CPU to Da Max” that came in recently. Only, that’s a really stupid idea on laptops, especially when running on battery, with no apps that need the CPU)<\/p>\n

    (NB: that was the same window, with the same tabs, as before I upgraded to 10.6.6 – I saved \/ restored the session. Whatever’s broken, the 10.6.6. upgrade currently seems the most likely cause)<\/p>\n

    Sadly, there’s no way out (can’t downgrade) and no way forward (no patches available yet).<\/p>\n

    i.e. the bad-old-days of Microsoft’s “auto-updates” and the critical bugs they often caused. At least Microsoft had the excuse they couldn’t test all 100,000,000 combinations of hardware – Apple doesn’t. They’ve only got a few hundred to worry about :(.<\/p>\n","protected":false},"excerpt":{"rendered":"
