Mac OS X 'Leopard'-related Discussion

Has anyone encountered problems handling JPEG's in Preview? I took a photo on my D70 as a JPEG, copied it onto the Mac and was trying to resize it / adjust colour info and save it back out as a regular JPG. When I got to the Save As dialogue and tried to browse it kept crashing Preview. I could repeat it over and over again to make it do the same yet I imported a NEF and did the same thing to it last night (saved out a JPG after colour tweaking) and it was fine.

Saving out to a different format (GIF) made it not crash.

Weird.

I just tried it a couple times with different .jpgs and I get the same result. The dialog box pops down, freezes, and then Preview crashes.

You should know better than to take jpegs on your D70. Tsk tsk. :p

Guys Leopard is running very slowly on my 1st gen Macbook. It's a core duo 2Ghz with 2gigs of memory.

All animations are slow, and I get poor battery life on leopard. Windows and programs start very sluggishly.

Is my macbook just not able to handle it?

I did an archive and install.

Do you think perhaps 10.5.1 will fix my performance problems?

Also maybe the whole os is slow because of my integrated gpu. I know on Vista if I ran on integrated graphics, the whole os was really slow till I got my graphics card back (I RMA'ed it) Could this be the problem?

I dont think so, Tiger uses the GPU for all graphical stuff as well.

The first thing i'd say would be try a clean install by moving all your stuff to another hard drive. but if thats not an option,

Defrag.... that helped Leopards performance big time for me. Disable the dashboard and 3d dock?

[freak_power]

Just to say...Great looking OS a big time ahead of Vista...

Did you just install it? It takes a while to index everything.

I have the same specs as you except 1.8 and everything is fine.

It's been on there for about 5 days. Tiger was much, much faster than Leopard.

[CPressland]

Yeah i'd advise a clean install then, because my system is almost twice as fast as with tiger :o

[.kvn]

Same here. My clean install is blindingly fast. Spotlight is faster, apps open quicker or at least appear to and I love the new features particularly Quick Look.

[Blaine]

but I did an archive and install. Should be just as good as a clean install.

Hehe.. yeah, I know.. it was just cause I needed a quick picture of something!

Blaine, I've been reading around a few other forums and some MacBook users have had the same issue and with an Archive/Install setup. Perhaps going for a clean install may alleviate the issue you are experiencing.

[DrunkenMaster]

If you browse an FTP site using the Finder, (clicked on link with Safari), you can use Quick Preview to view files on the server. It will likely need to download the file before the preview. I've been doing this with .DOC and .PDF files on a public FTP site and it works like a charm.

Coverflow even works in the FTP directories!

That's really unacceptable :/ An archive and install should be exactly the same as a clean install except it creates a folder with my files in it.

Since this has happened to my macbook and with the iMac's freezing problem I hear about, I am really starting to reconsider my wanting to switch from windows to macs.

The edit button is gone on my above post, so I have to make a new one. I just wanted to note that Leopard is draining my battery at about twice the speed that Tiger did.

RE: upgrade vs. clean install

My wife and I both have the same MacBooks that we purchased a few months ago. I used the upgrade method on hers and archive+clean install on mine. I have noticed hers lagging a lot when doing simple tasks. Mine has been running very smooth thus far. I personally have always preferred a clean install when moving to a new OS version on all my machines (mac, windows, & linux).

Anyway, just thought I'd share.

This adds to my previous post about tile-types. You no longer need to fiddle with the dock.plist to add any tile type you want. Just issue this command from Terminal:

To add a tile-type in the documents section:

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "spacer-tile"; }'

To add a tile-type to the apps section:

defaults write com.apple.dock persistent-apps -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "spacer-tile"; }'

You can change "spacer-tile" to whatever tile type you want. You can then move the new tile to wherever you want in the Dock. Also, by using this command you can have a Recents stack in your apps section (Good for recent apps). Spacer-tiles can also be added to the documents section.

Got it today, impressed with it (even though it's a buggy .0 release, same issue with Tiger)

Some of the animations were laggy, seems to have gone away now, and iTunes would crash and lock up (and stop me logging out), but it turns out it was my iPod causing that.

I noticed this when repairing my permissions:

But apparently we can look the other way when it comes to this according to Apple.

I have had the same permissions issue with Leopard but haven't tried again since updating to 10.5.1 but thanks for the post .Neo :)

I think I may have found a bug. Today the date on my calendar icon was showing yesterdays date till I opened iCal. It seems that the icon only updates once when the system starts up (I think this because the computer was rebooted yesterday)

[Menge]

i just updated to 10.5.1... is it just me or has the animation performance on Expos?/Spaces been MUCH improved on GMA950 MacBooks?:|| everything feels so smooth now. no bugs so far with the .1 update:DD

Blaine: yes the iCal icon is updated on logon, i think. if you leave it overnight it won't get updated, it seems:||

Spaces F8 is SO much faster now on my Macbook.

Okay, is it just me or has Leopard made transferring of files to External HD noticeably faster :D
