Cannot access external NFS mounts under Snow Leopard

I was previously running Leopard (10.5.x) and automounted an Ubuntu (9.04 Jaunty) Linux NFS mount from my iMac. I had set this up with Directory Utility and it was instantly functional and I never had any issues. After upgrading to Snow Leopard, I set up the same mount point on the same machine (using Disk Utility now), without changing any of the export settings, and Disk Utility stated that the external server had responded and appeared to be working correctly. However, when attempting to access the share, I get a 'Operation not permitted' error. I also cannot manually create the NFS mount using mount or mount_nfs. I get a similar error if I try to cd into /net/<remote-machine>/<share>. I can see the shared folder in /net/<remote-machine>, but I cannot access it (cd, ls, etc). I can see on the Linux machine that the iMac has mounted the share (showmount -a), so the problem appears to be solely in the permissions. But I have not changed any of the permissions on the remote machine, and even then, they are blown wide open (777) so I'm not sure what is causing the issue. I have tried everything as both a regular user, and as root. Any thoughts?
On the Linux NFS server:
% cat /etc/exports
/share 192.168.1.0/24(rw,sync,nosubtree_check,no_rootsquash)
% showmount -a
All mount points on <server>:
192.168.1.100:/share <-- <server> address
192.168.1.101:/share <-- iMac address
On the iMac:
% rpcinfo -t 192.168.1.100 nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
program 100003 version 4 ready and waiting
% mount
trigger on /net/<server>/share (autofs, automounted, nobrowse)
% mount -t nfs 192.168.1.100:/share /Volumes/share1
mount_nfs: /Volumes/share1: Operation not permitted

My guess is that the Linux server is refusing NFS requests coming from a non-reserved (<1024) source port. If that's the case, adding "insecure" to the Linux export options should get it working. (Note: requiring the use of reserved ports doesn't actually make things any more secure on most networks, so the name of the option is a bit misleading.)
If you were previously able to mount that same export from a Mac, you must have been specifying the "-o resvport" option and doing the mounts as root (via sudo or automount which happens to run as root). So that may be another fix.

I have a big problem with Lion and PGP. After upgrading from snow leopard to lion I cannot access my PGP drive which was generated under snow leopard. PGP does not start but gives a notion that lion cannot work with my PGP version. Solution?

After upgrading from Snow Leopard to Lion I cannot access a PGP drive which was generated under snow leopard. PGP does not start. When I try to start I just receive a message that Lion cannot work with PGP. How can I now access important and confifential informatio which I have stored in PGP (snow leopard). Do I have to move back to snow leopard. If so, how can I do this?

If you have this product,

you have to go back to Snow Leopard.
To re-install SL, back up your home directory, format and re-install.

Under Snow Leopard I used a WD My World NAS to back up my Mac Pro (Mid 2010). When I upgraded to Lion I am unable to access the backup because the NAS does not yet support AFP. I have now bought a Time Capsule and want to transfer the old backup onto it.

Talking to Apple Support Adviser was a waste of time on case number 239647273
Any thoughts or pointers?

Keep the old OS around and just kick the tires and test new OS. Apple has a history and habit of breaking support in things like this.
You can use TimeMachine as one level of backup, and even there there were changes with Lion, I would always recommend foremost backup clones of every volume. And clone (SuperDuper etc) can be stored on something like HP NAS Media Server which also was supporting TimeMachine, iTunes - until Apple made that harder and more their own proprietary format.

Rather than "upgrade" I would clone the system, and do a clean install, then allow Setup Assistant to import your files.

Front Row Incorrectly Reads iTunes Metadata under Snow Leopard?

There is a serious problem with Front Row under Snow Leopard. The program is unable to correctly read the TV metadata from iTunes and does not correctly filter/organize the data. TV episode/season/title data is not read resulting in a completely disorganized library. All files are viewd as "movies" whether they have been tagged as TV shows or not. I had a sizable libray of videos that was perfectly organized under Tiger. Under Snow Leopard my entire database has been blown up- most TV shows appear as "Untitled". I'm sure they are MacMini users who have integrated their computers into their media playback systema s I have and am hoping Apple will provide a fix for this issue which totally undercuts one of the main reasons for integrating the Mini into one's home theatre system. Does any have a fix or simple work around. Come on Apple-- don't turn into Microsoft on me!

I recently purchased a used iMac (from 2006), that the previous owner had upgraded to Snow Leopard. I already have a MacBook Pro. To explain, I purchased the iMac to set it up as a media center computer, connected to my external hard drive and synced with AppleTV. I used Migration Assistant to move my files onto the iMac, but Front Row is now showing all the errors you described.
1. It is VERY slow to open. Clicking Menu on the remote, and you wait 15 seconds or more for Front Row to open.
2. Even though iTunes is directed to my external hard drive, Front Row shows Source as my Macbook Pro.
3. TV shows are out of order. On my Macbook Pro (10.5.8) all shows are listed from first to last, from top to bottom. On the iMac (10.6.4) they are listed last to first, top to bottom.
4. Some TV shows that are clearly in iTunes (purchased from iTunes) do not appear in Front Row at all.
5. The unwatched content blue dot remains even after watching something all the way through to the end. After watching them in Front Row, iTunes does not show them as watched either, but instead has the half blue dot, as if they were unfinished.
6. iTunes is also badly affected: I now have a large number of TV shows in the Movies section, and attempts to reorganize them in the folders on the external where they are store fails. It's a complete mess, and it seems like its deliberate that we cannot reorganize it ourselves.
So what used to be a very lovely program has become a horribly messy, PC like, application. Which made the whole point of setting up a special computer just for media a total waste of time and money with Snow Leopard installed.
If a fix is not forthcoming, I'm probably going to uninstall Snow Leopard, and reinstall Leopard. Everything worked fine there for me.

No 802.11n on early Intel iMac under Snow Leopard

Hello,
After installing Snow Leopard on my white Intel iMac (first Intel iMac model) I have lost 802.11n functionality. I had to patch the iMac under Leopard with the AirPort Extreme 802.11n Enabler to get 802.11n working (http://store.apple.com/uk/product/D4141ZM/A). Snow Leopard appears to of changed the Airport Extreme settings, and under system profiler it just shows: ‘Supported PHY Modes as 802.11 a/b/g’
I can no longer use the 802.11n enabler under Snow Leopard as it comes up with an error message "You cannot install AirPort Extreme 802.11n Enabler on this volume. This volume does not meet the requirements for this update." - this is due to an Airport Extreme 2007-002 upgrade being required (http://support.apple.com/downloads/AirPortExtreme_Update_2007002), which also won't install under Snow Leopard.
Help! Is this a known issue and will Apple be releasing a Snow Leopard compatible 802.11n enabler? OR, is there a work around/fix under Snow Leopard.
Essentially, accessing my home server for work is a nightmare as 802.11g is just not fast enough for the media files I work with.
All help would be greatly appreciated.
Regards,
Graham Johnson.

I am a bit confused as to which iMac you are trying to use with 802.11n.
You say that you have the first white iMac that was Intel. But the first three white Intel iMacs do not have 802.11n capabilities; neither the Early '06 Core Duo, the Mid '06 Core Duo, nor the Late '06 Core 2 Duo CD have AirPort Extreme cards capable of 802.11n. But you profile is showing a 2.16 GHz iMac C2D which is Late '06 and does have the AirPort Extreme card with 802.11n capabilities.
Is that the Mac that now appears to have lost this capability?
What does Apple say? Did you buy Apple Care? Is it still in its last weeks of warranty?

Backing up an encrypted drive with Time Machine under Snow Leopard

In a nutshell, my question is “Can I back up an encrypted drive using Time Machine under Snow Leopard, and if so, how do I access its data from a previous day?”
I have a 1Tb USB drive connected to my MacBook, which runs Snow Leopard. The drive is formatted as Mac OS Extended (Journaled). This drive is included in the drives that Time Machine backs up. I used Disk Utility to create an encrypted drive on the USB drive (998Gb), also formatted as Mac OS Extended (Journaled). The encrypted drive is not on TimeMachine’s list of excluded files/drives.
When I go into Time Machine, I can see the USB drive and the encrypted drive in the side bar. I can access the files on the encrypted drive as long as I’m looking at how it stands now. But if I move backward in time, the encrypted drive is grayed out and inaccessible. If I click on the USB drive, I get a window that tells me it is 75.9Gb in size, and nothing else is available to me.
When I open the back-up drive in Finder and navigate to Backups.backupdb > macbook name > some date and time, I see my MacBook’s hard drive and the USB drive. The encrypted drive is not shown. When I click on the USB drive, I see an entry for drivename.sparsebundle. When I click on that I’m prompted for the password for the encrypted drive. When I enter it, I get a warning telling me that the disk image could not be opened and that the encrypted drive has no mountable file systems.
Is my encrypted drive really be backed-up and if so, how do I access the backed-up data?

Having received a bunch of views but no replies over the last 5 days, I decided to venture into my local Apple store and ask this same question. The response I got from the geniuses was that you can't get a reliable back-up of an encrypted drive using Time Machine under Snow Leopard. So, my only alternative is to copy the encrypted drive's contents elsewhere, unencrypt the drive, and then copy the contents back. This is what I expected, but not what I wanted to hear.

HP Officejet Pro 8500 Wireless Won't Scan Under Snow Leopard

After installing Snow Leopard, my new HP Officejet Pro Wireless 8500 all-in-one printer won't scan. It delivers the following error message: "No Scan Options - refer to device documentation".
Also, when I attempted to check and adjust scan settings using HP's Scan Destinations program, that program hangs and cannot save any setting changes. Then I have to use "Force Quit" to stop the program from hanging up while saving.
HP's software update reports the printer software is up to date.
It appears there are a ton of printer problems appearing for people after installing Snow Leopard, but I sure would appreciate any help on solutions if someone also has this problem.
Thanks much.

I also just tried connecting my 8500 wireless printer directly via usb and then downloading the HP printer drivers from Apple downloads and reinstalling.
The install hangs nearly forever on the final step, but eventually says the driver install was successful. However, then when connected via usb, I am unable to print. Printing works when you reconnect via the wireless on the 8500.
So connecting via usb and reinstalling HP printer drivers does not solve the issue. And it's puzzling, because the list of supported printers under Snow Leopard lists the Officejet Pro8500 Wireless as supporting both printing and scanning.
Somebody has it wrong.
If this scanning problem continues very long, I may be forced to uninstall Snow Leopard, because my printer is brand new.

Canon iP6700D Tray Choices Disappear Under Snow Leopard

I have a Canon iP6700D. In 10.5 and earlier, one could select between the automatic sheet feeder and the cassette through selections under "Quality and Media". Those options seem to have disappeared under 10.6.1 using the September 11th Canon printer driver. Nosing about in Google, others seem to have the same problem with this and other printers under Snow Leopard. I've tried uninstalling the printer and re-installing but it hasn't helped.
Settings made under 10.5 and saved still appear in Snow Leopard, and are still able to access the cassette and the sheet feeder, but I can't find a place to CHANGE that for saved or for new settings.
Can anyone tell me where to find this setting, or where I might find a patch that will fix the problem?

The v10.26 driver for the iP6700D still has the Paper Source menu under Q&M on 10.6. I can only think that something is conflicting with your installation of the driver. I would trash the contents of the BJPrinter folder, located in HD > Library > Printers > Canon. Then install the v10.26 driver again and see if the menus are present.
There were two versions of printer drivers available for 10.5, v5.8.3 and v10.xx. If you had the version 5 installed and had presets based on this driver, then they will not work correctly with the v10 driver on 10.6. You should Delete these presets and create new ones once you get the Q&M menu appearing on your install.
Final note. You should be posting this question on the Snow Leopard forum. This forum is for Leopard printing and scanning issues.

Problem with Backup 3 (3.1.2) under Snow Leopard

Okay so I use Apple's Backup 3.1.2 which is free to all .Mac members as you know to back up all of my Macs to a NAS (networked drive). Anyway, under Snow Leopard this stops working. When you try to tell it to save the back ups on a mapped or mounted network drive it will not let you choose it and defaults back to the Macintosh HD. Under Leopard it had no problem doing this. What is interesting is that if I reinstall Backup 3 it will start to work and allow me to save to the network drive but as soon as Backup tries to do its backup by it self AND if the network drive is not mounted for some reason (has to be mounted manually), BackUp breaks the save point with the NAS and you can not tell it to save to the NAS again. As you also probably know everytime you restart your mac all the mounted network drives are not connected until you manually open them your selves. Under Leopard Backup would actually say "Waiting for Christian_BackUp" until I would open it and then it would start the backup automatically. Please help me get this working...I can not use Time Machine because I need a smooth, reliable, and working way to back up to a NAS.
Thanks for your help in advance!
PS: I have confirmed this problem on three macs all running Snow Leopard with different NAS setups.

Whenever I put my Mac to sleep Backup 3.1.2 stops running scheduled backups to my iDisk automatically. This behavior started only after I installed Snow Leopard. They always ran just fine under Leopard whether I had put my iMac into sleep mode or not. If I reboot now and never put my computer into a "hard" sleep the automatic backups work fine, but as soon as I manually select "Sleep" mode the automatic backups stop happening even if the computer is awake when the backups are scheduled to occur.

Problems with AppleWorks drawing docs under Snow Leopard

Since I installed Snow Leopard, I've encountered two major problems:
(Problem 1) AppleWorks gets corrupted when dragging a picture file (.jpg or .png) from the desktop into a drawing document. Various dialogs (e.g. "Format : Document..." or "Format : Ruler : Settings ..." or "Options : Object Size ...") become uneditable. These dialogs will display blank boxes instead of the given object settings, and nothing can be entered into these boxes. AppleWorks must be shut down and restarted in order to continue work.
(Problem 2) When a formula (i.e. an equation) has been created in a MathType window, selected and copied, it takes ages to make AppleWorks the active application (spinning rainbow coloured ball appears and keeps spinning for a long while). Thereafter, it takes another century to get the formula appearing in the AppleWorks document when selecting the command "Edit : Paste".
Everything worked still fine under Leopard; under Snow Leopard it's a desaster.
p.s.
I've produced thousands of work sheets for my Maths teachings using the Drawing module of AppleWorks in combination with MathType (Design Science). Now I'm stuck since there is no decent successor of AppleWorks available:
* iWork doesn't feature a drawing module.
* EazyDraw doesn't collaborate with MathType (i.e. no OLE; inserted formulae cannot be edited by double-clicking).
* OpenOffice doesn't collaborate with MathType.
* Micro$oft Office doesn't feature a drawing module.

Welcome to Apple Discussions
I don't use AppleWorks as much as I used to & I've never had a need to use MathType, but I just tried dragging 3 images - a .png, a .tiff & a .jpg - to a new AppleWorks draw document. I had no problems resizing them using Format > Scale by percent & I had no problems using any of the other dialog boxes you mention.
Some basic troubleshooting you might try:
Whenever you do an update, it's a good idea to do two maintenance tasks, one for the system (Repair Permissions) and one for AppleWorks (delete preferences). (Thanks to Barry for this way to format this very common answer.)
To Repair permissions in 10.4.x, launch Disk Utility, found in the Utilities folder in your Applications folder, click on First Aid, then on Repair Permissions.
To delete AppleWorks’ preference files, go to HD > Users > Library > Preferences. Find and delete the file com.apple.appleworks.plist. Find and open the folder AppleWorks in this Preferences folder, then delete all of the enclosed files (with the exception of the Button Bar Preferences if you have customized the Button Bars). AppleWorks will recreate the preference files as it needs them. You should do this step anytime AppleWorks crashes or you force quit it.
The slowness is likely the "Recent Items bug" & it has been around since AppleWorks 6 was released in March, 2000. It can make it appear that AppleWorks has frozen or failed to launch. The user tip by Dale Gillard, AppleWorks slow? Spinning ball appears?, explains a lot.
Could you send me a copy of one of these worksheets? Perhaps I can see if I can easily duplicate one in Pages/Numbers/Keynote. Even though iWork doesn't have a draw app, all of the apps do have basic drawing capabilities.

Problems in creating PDFs from Indesign under Snow Leopard

The Acrobat PDF Printer does not work under Snow Leopard anymore.
Adobe gives this alternative:
http://kb2.adobe.com/cps/509/cpsid_50981.html
After an update to Acrobat 9.1.3 PDFs should now be generated through a new "Save as Adobe PDF" option under the "PDF" button in the system print dialog.
This does not at all work in Adobe Indesign with it's proprietary print dialog. The PDF-Button is only available in the system print dialog (I know it is accessible from within the Indesign print dialog panel, yet clicking on the PDF button and selecting "Save as Adobe PDF" is ignored).
To make things worse: If you follow the advice to delete the Acrobat Printer from the "Print & Fax" panel this deletes the ADPDF9.PPD from the Library/PPD folder! You even cannot produce .ps files and distill them manually. Fortunately I was able to restore the ADPDF9.PPD from a backup.
This is really annoying: How can Adobe state everything works fine under Snow Leopard if you are not able to create PDFs any more? Or did I miss something?

Hi.
make this.
1. Go to the Apple> System Preferences...
2. Open the "Print & Fax" preference panel.
3. Select the Printing tab, to get to the printers list.
4. Select the printer "Adobe PDF 9.0".
5. Click the options and supplies button.
6. Choose the Drive.
Now I have reinstalled Leopard. but first like a Drive I have listed only a "Generic Printer".
I tried to reassign it ADPDF9.PPD but is not recognized and automatically resets to a generic printer.
So after some tests that I have found here

I have reinstall leopard
This has been my problem.

Will it work to recover from a Time machine data backed up under Snow Leopard?

Hello,
Mine a Mac Book Air that has 2.13 GHz Intel Core 2 Duo and RAM: 2GB 1067 MHz DDR3.
I have time machine back up on an external HD.
Once I install the Lion os, would I be able to use the backed up data under Snow Leopard to an external HD if any eventualities on a later date? Data such as photos in Aperture library or folders with Mac version of Windows Office 2008.
[The time mechine backed up data was under Snow Leopard and my Mac Book Air now has the Lion OS]
I understand as soon as I upgraded to Lion I should create a new back up with time mechine but in case if that is not done......
I hope your understand What I mean..
Regards

What you propose should work. There could be problems with data for applications such as Mail where the application version and format of the data changed in Lion.

EHD under snow leopard not seen under maverick

Hello Apple Community,
I've recently bought a brand new Macbook pro under Maverick. The External Hard Drive, used on my old Macbook air under snow leopard, is not recognized by Maverick. That's strange because it is seen and can be used on the other laptop, but not on the new one.
In the finder preferences, the box "show EHD" is checked.
But when I use the disk utility, it sees only the hard drive on the laptop, not the EHD...
Does anybody have a solution for this?
Thank you>

FreeHand MX on the new Mac Pro under Snow Leopard?

Just wondering if anybody is managing to successfully run Adobe (Macromedia) FreeHand on the new Mac Pro under Snow Leopard?
We often need to access a lot of archived FreeHand files and are wondering whether we should keep an old G4 tucked away just for this job when we next update our Macs.
Thanks,
Jona

Hi jona;
A quick Google search produced a number of sites such as this one that basically say that freehand doesn't do so well on Snow Leopard. You suggestion for maintaining an old G4 sounds like a good one to me.
