GLITCH ALERT!!

Like a fool; i upgraded to snow leopard straight away...
It keeps dropping the link to my Wi-fi router on average every 5 minutes, rendering the internet experience utterly rubbish.
I have now tried everything- including changing routers :-(
A quick search of the forums reveals I am not the only one!
It has been a couple of weeks now, and I check for a 'software update' daily, but no luck so far!
Come on apple, pull the ol' thumb out! …More197 of 217 people found this useful

needs improvement
Written by KH from Dunbar
Oct 6, 2009
Reading around it is clear that some people have no problems upgrading, and yes the actual process of installing the new software is reasonably quick (under an hour) and without any glitches.
The problems began after that: Safari, iPhoto, Mail all crashed without warning doing simple things like opening web pages, adding attachments to emails etc. Photoshop CS3 (not supported, I know) has crashed more times than I care to remember, taking hours of work with it.
Things are slightly better with the 10.6.1 update, but I wouldn't rush in yet. There are still crashes and my Canon iP4300 printer interface doesn't work. Yes, it is supported, but it is incapable of selecting anything other than the default paper tray. For envelopes etc this is necessary (thankfully this can be done using a button on the printer).
There are space savings so if this is an issue for you it might be a persuader. Some programs do seem to launch quicker, and there are a few nice refinements; however, the failings still outweigh the benefits for me.
I would suggest at least another update is needed! …More139 of 156 people found this useful

Avoid at all costs

If you are in the graphic design or print business and rely on Postscript Type 1 fonts or practically any version of Helvetica Neue, including OTF, then avoid this update like the plague until Apple sorts these problems out (don't hold your breath, though: their response so far has been to stamp their feet and blame Adobe). …More

Anxiety

Snow Leopard appears to have been a rush job – I guess Leopard was a little slow.
This version is faster and does contain some new functional gimmicks. The problem is that someone seems to have forgotten that for some of us the mac is more than an entertainment center. When fonts, printers, and pdfs no longer work – anxiety sets in. Some consultation with Adobe before releasing this upgrade might have helped! …More23 of 25 people found this useful

Wow it shuts down a bit faster and wow it starts faster(not so sure) yes my mac now eats power and yes 3rd party software hangs and crashes a lot. Would not mind but my new mac book (only 2 months old) has more problems than before the upgrade. I have been a mac user for along time and this appears to be a big con to get £25.00 off a lot of mac fans. Anyone wanting to throw away £25.00 then dont buy the upgrade, post me the money and i will have a night out..... …More

What a shame
Written by AD from Stanford le hope

Since upgrading my internet often freezes. Something which never happened before the upgrade.
My calender and address book no longer sync with itunes, and thus are no longer available on my ipod.
This feels more like a microsoft non-upgrade than an Apple upgrade
I haven't noticed the alledged speed increase in system start up and shut down
Plus points ........ It loaded easily …More14 of 16 people found this useful
