i installed the developer preview of os-x lion some weeks ago. following are my first impressions. let me know how you think... performance: at first i thought lions performance sucks, but mdworker and kextcache processes are re-initializing spotlight right after installation which slows down the system and heats up the cpu. after two hours of fan-noise and heat the system seems to be fine and is running smoothly now…

re:calendar for multiple gcal accounts Try BusyCal though I am in a similar situation and havn't found a good fit.

BusyCal is what I'm recommending to all of our Mac-based employees and what I use on my personal machines to handle dozens of calendars across several Google & Google Apps accounts. +1 recommendation for BusyCal; absolutely worth the license.

How is the backwards compatibility in general? I got a Oracle 10g database running on SL that I am particularly worried about. I got it anyways - will have to do a full backup and find out I suppose. Speaking of 4GB downloads - OS X still does not have something like http://en.wikipedia.org/wiki/Background_Intelligent_Transfer... which can utilize priorities, throttling and do idle bandwidth downloads. That means my…

I'm on SL and I also depend on Oracle 10g, so thanks for the note on the Seg Fault, that would be showstopper moving to Lion.

Now, I get the ulimit error on SL too, that's just that your "oracle" user is not authorized to set ulimit that high (it's in your oracle ~/.bashrc). You probably followed the installation instructions from Pythian (http://www.pythian.com/news/1937/quick-install-guide-for-ora...), just like I did. If you didn't get that error before, maybe the Lion installation has reset the max processes limit.

Here's how to check the current value:

  ojosilva@snow:~$ sysctl kern.maxprocperuid
  kern.maxprocperuid: 266
Change it like this (so it matches the ulimit -Su and -Hu values in oracle's .bashrc):

  sudo sysctl -w kern.maxprocperuid=512
Maybe that will cure your segfault. Read thru the Pythian page and recheck all your sysctl parameters. Let me know how it goes.

A small word of warning: I mostly use Windows 7 on my MacBook Air, but I decided to upgrade anyway. Unfortunately for me, the upgrade rendered my Bootcamp partition inaccessible (it doesn't show up in startup disks, and does show up in Disk Utility, but cannot be repaired).

Wow, thanks for the warning. I was just about to upgrade. I have an entire drive devoted to Boot Camp I'll probably be okay? It looks like there is one error situation detected during install: http://support.apple.com/kb/HT4649 The anandtech review implies that boot camp assistant works and the boot camp drivers (a separate download) are now 4.0 but I can't actually find them, I assume the apple updater has them. htt…

Many other people have had success, but so far there doesn't seem to be a common thread between the people who've had failures.

I have been a Windows user since I started using computers. I am thinking of purchasing a Macbook Air. As a young programmer (going into fifth year of college), would anyone recommend this laptop?

I'd wait a year till you graduate, if you still need to buy a computer, buy the 17in and add an SSD if you are going to be doing programming, otherwise either the 13in air or 15in MBP will work fine if you need one NOW. The 13in MBP is pretty low end without upgrading many of the components. MBPs have tremendous resale value (especially the higher size models), so don't feel so bad about spending a few extra bucks on…

Good lord, no. Stay away from 17", you might as well be lugging a desktop around. 13" is the sweet spot for me, MBP or MBA depending primary on memory needs and workload.

Tried to update to Lion: couldn't do it. Tried to update Snow Leopard so I could update to Lion: computer now kernel panics on boot. Tried to reinstall Snow Leopard from DVD: turns out the disk drive is broken. Tried to install a Linux distro from a USB key: turns out they're nearly impossible to boot on a Mac. Still haven't figured out how to do it. This went well.

I tried to install Lion after purchasing it from the App Store. It kernel panicked during install and then TRAPPED ME at the installer. Despite restarting, using disk utility, etc, I was stuck.

I erased the partition and tried to install again. Kernel panic. I tried putting Lion on a USB drive. Again, kernel panic

In my desperation I just kept running the installer over and over again and ONE TIME it worked. I was so pleased - until it kernel panicked on restart.

Still, it's working now. It will kernel panic every now and then. When I look at the logs for the kernel panics, the last kext loaded almost always has to do with networking/WIFI. This seems to be a relatively common.

The only big drawback is it ain't cheap. You can even run Windows on if you really want.

Having an external DVD drive to install it is advised though, it is really difficult to do it with a USB drive.

If you open the Installer.app package, you'll find a DMG in there. You can then partition your USB drive/internal hard drive/external hard drive with a 5 GB partition, and restore the DMG onto it via Disk Utility.

You boot from the partition, and after installation, delete it and extend your primary partition (if you partitioned your internal hard drive).

The new MacBook Airs are two times faster than the last generation MacBook Airs. They are also faster than the high end 17" MacBook Pros from 2010. [1] They are about as fast as the low end 13" MacBook Pro.

The biggest drawback, by far, is the insanely low RAM. Anything less than 8GB is unusable for me, and I certainly can't be the only one.

Honest question: Are there any ultra-lightweight laptops that handle 8GB?

lenovo x220 can take 8

I have recently tried (yet again) to make some bootable USB keys on a mac. Turns out you have to convert iso to UDxx:

    $ hdiutil convert -format UDRW -o bootable.img bootable.iso && dd if=bootable.img of=/dev/disk1 bs=1m # Check the disk number with diskutil list!
If it still won't boot, rEFIt (or Boot Camp, naturally) help with BIOS emulation.
