Preview very slow with .nef photos

My preview works well for .jpg but not .nef.
Open folder, select 'all' right click, open with 'preview'. Very slow & jerky.
Used to work fine with .nef in Mt. Lion.
Any ideas?

Same issue here, and 10.10.2 brings no solution… Haven't you heard yet, Apple is the new Microsoft?!
Anyway, here a few tips to speed up Preview at least a bit, so one can use it for work again:
tip1:
Delete /Library/Preferences/com.apple.windowserver.plist
Delete ~/Library/Preferences/ByHost/com.apple.windowserver*.plist
Shutdown OSX
Startup, immediately press and hold the P and R keys while holding down the option (⌥) and command (⌘) keys before the gray boot screen appears, which resets the PRAM
tip2:
Turn off "Smooth Text and Line Art" in the Preferences. Of course, that's really sad, because PDFs then look terrible, but at least they are easier to work with.
tip3:
For just viewing, use QuickLook: in the Finder, select the PDF and hit [SPACE]. Strangely, QuickLook isn't affected by the bug.
Anyway, those workarounds helped me a bit (thanks to those who posted them), but of course it's no proper solution. The last option would be to go back to Mavericks.
I heard the problem was reported to Apple when Yosemite was in beta, summer 2014. Nothing happened so far. Apple really has to get its act together…

Thank you very much for your reply gdgmacguy :) I did all you suggested apart from restore as new device . Didn't know I could do that . After restore I did restore from back up only, as I didn't want to end up without contacts details on my phone. If I restore as new device how do I get my all contacts? Still will have to use back up? Sorry if it sounds like I don't know what i am doing, i just have no one to ask who would know. Thank you

My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words.

My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words and looks them up via dictionary. I currently have a wireless mouse connected and I am still having the same problems.
I fee like I may have a virus or my laptop is perhaps being accessed remotely. All of the sharing options are unchecked.
HELP PLEASE
Very worried!!

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

Imac is very slow with downloading mail

My imac is the ast weeks very slow with downlaoading mail.
I am using mail 5.3 from apple
Nothing has recently been chanched in my internet setting or internet speed
Anybody an idea what can be wrong?

Hi, I worked out what you recommended, but I do not see any difference at speed.
Mail starts normal, though that is also somewhat slow,
Before it has finished downloading mail (even is there os no mail!) it takes sometimes 2 minutes!
Also there was no"boing"when starting up, with following your procedure, is it normal?

AE CS6 very slow with footage

Hi guys,
I am using AE Effects CS6 (11.0.4.2) on a new Macbook Pro with these specs:
2.8 GHz Intel Core i5
16 GB MHz DDR3
Intel Iris 1536 MB
The problem I am having is that when imported footage is visible as footage or a layer, AE becomes very slow with every click of the mouse on either the timeline or the footage in the viewer itself causing the color wheel to appear, often for 30 seconds at a time. Strangely, dealing with the composition has no issues.
Any ideas guys?
Thanks in advance

Try transcoding the footage to a production codec and see if that makes a difference.
Like, use the Adobe Media Encoder to make them something like QuickTime with the PhotoJPEG codec.
See if that helps with the performance.

PLz tell me why! How to deal with it !

Unless it's confirmed officially that your phone is defective, then you can ask for a replacement. Or you have to live with you. However you can trade it for a new one if you don't care the price drop.

Ftp.belnet.be mirror very slow with updates

The mirror that is closest to my location, ftp.belnet.be , seems to be very slow with updates for AL.
XFCE4 was updated to 4.2.3 around nov 10 on archlinux.org.
11 days later xfce4 4.2.2 is still on belnet , and not replaced by the new version.
Since it's also a fast and reliable server, i don't mind waiting a few days, but more than a week is TOO long.
What's the use of a bleeding edge distribution when you can't get updates that have been available for more than a week ?
For now, i have fallen back on archlinux.org , but will look for another european server.

In contrast with the name, that server doesn't seem to have ANY arch packages anymore.

TC VERY SLOW with backup

Suddenly, TC is VERY SLOW with backup. In fact, I went in and discovered that it had not completed a backup since July 19th. I started one last night and when I checked this morning (about 10 hours later) it was 70MB into a 2GB backup. An hour and a half later it was at 100MB and an hour after that it was at 125MB. At this rate, it's going to take a couple of days so I cancelled the backup (it then went into it's housekeeping routine of "cleaning up"). BTW, I had quit all applications before I started the backup and TC said I had 454GB of free space. I'm not running any AV software and I have OS 10.6.8 I'm on an Ethernet network to the TC (I also have Airport active - could that be an issue? It never was in the past)
Any ideas would be appreciated.

So...I may have panicked when I saw all of those empty folders in my Document folder...however, when stopping the backup to TC (the 'cleaning up' process of stopping took more than 2 hours), my folder contents showed up. I guess that process takes the file index pointers offline or something so I couldn't see file contents during the process. I then did a permissions repair and a verify on my hard drive.
But the bad news is that my Time Machine is still showing EMPTY! I currently running disc utility 'verify' on my TM backup volume (it says the projected time to complete is 3 days!!!) The disc utility says that there are 4,000,000 files in the backup volume - I just can't see them. When I ran Time Machine, it only has 'today' - no prior backups - even though Time Machine Preferences reports that the oldest backup is August 1, 2010 (one year ago) and that the last backup was July 19, 2011. They are not there.
I've seen some other posts like this, so I don't think I'm alone with this problem.
The good news is that all of my folders and files on my computer appear to be intact. The bad news is that previous Time Machine backups are not there (or they can't be seen - even though the 1TB backup volume is in fact half full).

One possible solution would be to organise your inbox into folders.
Its never relly good on any system to have one folder that has everything in it.
Try going to you web gui for that mail account and organise your folders and move mails from your inbox into corresponding folders for better organisation.
Several folders containing the same amount of one folder will usually load a little quicker as the folder may not be accessed to download its content unless veiwed.
So having 10 folders with organised content, and you inbox as an area thats to hold only new emails would work much much quicker with imap.
Most imap servers will only update the contents of a folder when its veiwed.

Time machine very slow with mountain lion

Time Machine backups seem very slow with Mountain Lion.

Same problem here. I just upgraded from Lion to Mountain Lion. I only got 19 GB of space, but Time Machine wants 10 hours, whereas in OSX Lion a full backup would take just under an hour, and incremental updates were lightning fast.
I even sat it up to do it overnight, but on 8 hours it was only half way through only 10 GB. I can't live with that in the future.
Im trying to backup on a SD card which seems to work very good in Lion. Im on a 2012 Macbook Air using a SSD.
My bite of the apple has been somewhat sour. I tried reformatting the SD card, well knowing that I would lose old backups. But still the backup is extremely slow. Now I can't install Lion or Mountain Lion from scratch without having to wait 10 hours for TM backup or installing tons of applications and settings again. Bummer. I'm never going to early adobt a OSX upgrade again.

Shell recording takes place very slow with nouveau driver on gnome

Shell recording takes place very slow with nouveau driver on gnome(specifically gnome-shell).But when I used the nvidia-prop. driver,it just recorded fine.Are any other arch+nvidia-card users experiencing the same issue or it has got to do something with fps in dconf.(or it is a specific problem with my nvidia card).

It happened to me and has been for a long time. I got a new laptop about a month ago -- an i7. Though it's not as long as it was on my old desktop, it happens on this machine too. It happened right from a fresh install. I think it's just what Gnome does. I have no answers.
