Thanks to both Owen and Marcus for the good reports... While I've never
dreaded an OSX update like I have Winderz major releases, I have always
avoided being an early adopter... I might just take the plunge.
I'm wondering why VM compression hasn't caught on sooner? Has the
physical memory curve kept ahead of it well enough, or is the
compute-cost simply too high?
My mother-in-law's 2009 MacBook (not pro) is grinding a lot on VM
(mostly from web browsing)... I was going to look into possibly
downgrading her Safari/Firefox to an older version that might not be as
memory-hungry, or putting in some extra memory... but maybe upgrading
her system to Mavericks will provide the needed relief?
Except for the very unfortunate codename "Mavericks" it sounds very
promising... supposedly the name came from a Surf Beach near Half Moon
Bay, possibly suggesting "a new wave" in OS... despite apparently
being very similar to Mountain Lion, maybe it *does* portend a "new
wave". One has to wonder "did they just run out of Big Cat names?" in
the same way that they are running out of decimal digits (10.9) or does
this signify a significant change in direction (gearing up for a big
change in 11 and naming after surf beaches for the next generation?).
Sadly I can't hear the term "Mavericks" without hearing it in Sarah
Palin's pinched Wasila-Whine of a voice. I'll try to superpose the
image of a young James Garner making some dry, witty remark near the end
of a poker game on a riverboat instead. And who knew that Roger Moore
was on that late 50's TV western as cousin Beau Maverick?
Just converted to Mavericks and it seem great. And the upgrade was
free .. not sure why.
Steps:
First
- Clean obsolete kruft from computer. OmniDiskSweeper (free) is very
useful.
Also look at apps finding old and unused apps especially ones unlikely
to run.
Delete with AppZapper or similar .. need to remove prefs etc.
- Build a Superduper bootable backup. This is useful both as a
fallback, and if you
want a clean build, you boot from that and have the installer build on
your
internal boot disk. Probably need to clear/format/repair the disk w/
DiskUtil.
- I searched for a "how to migrate to Mavericks" article which
included all that
Then
- Go to App Store and download installer (takes quite a while due to size)
- When downloaded, pops up the installer. You can quit it and install
later if you'd like, in Apps folder
- Took quite a while to install as well, but seemed to do a sweet job
- Initially asked for lots of permissions and other transition
annoyances, but not bad.
- Smoothest install I've ever had.

My performance problems were solved (pushed back) with 8MB of

I feel like a HD upgrade (the one in it fails, my data hoarding

machine) that SSDs will be much more affordable.
OSX Mavericks now has compression in the virtual memory system.
I've been doing parallel builds all day and I see the Activity
Monitor regularly showing 2GB of compressed memory (on an old 4GB
2009 era MacBook Pro). If that had to hit disk, the system would
grind to a halt, but it doesn't. It seems to work well.

P.S. Linux has had this for a while in various forms for a number
of years, e.g compcache.
