Removing Classic before upgrading to Lion

My Intel Mac has a lot of old Classic stuff on it, as the result of using Migration Assistant from an older Mac. Before I upgrade to Lion, I have been eliminating or replacing old PowerPC apps. I also want to clean out old Classic stuff. Some of it easy to identify. But I'm not sure about one area in particular.
I have a folder labeled "System", which has an X on the folder icon (for Mac OS X), which contains the subfolder "Library". I also have a folder labeled "System Folder" without the X. It contains a lot of things which I can definitely identify as Classic (Mac OS 9).
Is this "System Folder" left over from OS 9, and can I delete the whole thing?
Thanks,
Marcia

Kappy, thanks for the very quick answer. I did remove that folder, and everything works fine. But I have a further question.
I now see that the folder labeled "System" which has in it one subfolder labeled "Library", is almost (but not quite) the duplicate of another top level folder labeled "Library". See simple hierarchy below. Is one of these also left over from OS 9?
MacIntosh HD
     Library
     System
          Library
And perhaps a better question, when I upgrade to Lion, will these folders be overwritten by new ones, and is all my worrying a moot point?
Thanks again,
Marcia

I'm using iPhoto 11, and instead of seeing my images in the main view, I see only outlines. (Had same problem in iPhoto 10 before upgrade to Lion Help!
I'm on a Macbook Pro and all of my software is up-to-date.
The photos and events, etc. appear to be present in my photo library, but I cannot see the actual images--only an outlined placeholder.

Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to rebuild the thumbnails. This can take 3 or 4 goes to work.

before upgrading to Lion, I switched from MobileMe to iCloud. At that time I used my MobileMe user name and password. I purchased additional storage space to 20GB. I was unable to send any emails during this time. After researching, I upgraded to Lion and changed my icloud mail usuer name and password from the original I used from mobileme. How do I get my upgraded storage to my new account. I intend to delete the first one.
Please help!

Welcome to the Apple Community.
Unfortunately you can't, the additional storage belongs to your first account, you can't transfer it.

Is a bootable clone necessary before upgrading to Lion (also Parallels 6)?

I'm thinking about upgrading to Lion on the MBP and the MacPro where I am running Parallels 6 with Windows 7.
Two questions:
1. How bad of an idea is it to do this without running a backup that includes a full bootable clone? I have a full backup of the machines but I think (?) someone advised doing a bootable clone before doing this upgrade. Not sure but wondering if anyone has any good advice on this. I guess the need for the bootable clone (assuming I am moving to Lion) would be in case I need to reload all the settings and everything from the year and a half I spent getting everything to my liking (no small amount of work)? I mean, I wouldn't re-load the bootable clone and then only work off of Snow Leopard so I guess (?) I am asking if there is other info in the bootable clone that makes it different from a normal backup in such an instance.
2. Does anyone know of any definitive documentation that tells me whether to upgrade to Parallels 7 first or if I go to Lion first for the upgrade? Does one need to go before the other?
Thanks.

If your Lion upgrade hoses, like it usually does for those upgrading over a complicated Snow Leopard, a hold the option key bootable clone of Snow Leopard on a external drive will get you using the computer in the time it takes to boot off of it.
It will also allow you to completely erase the internal drive and reverse clone Snow Leopard right back on.
If you do have to erase Lion, make sure you do it via the Partiton tab, so the entire drive is erased, not just the Lion OS X Partition.
2. Does anyone know of any definitive documentation that tells me whether to upgrade to Parallels 7 first or if I go to Lion first for the upgrade? Does one need to go before the other?
You'll have to talk to Parallels, but if the software works with 10.6 and 10.7 then it's best to upgrade to the 10.6/10.7 version on 10.6 (make a clone first before doing anything) then checking it out well before updating the clone.
Take your time, investigate all your software before making a leap, a clone or two will most certainly be of valuable assistance.
Move slowly and carefully, don't do too much at once or you won't know what is causing your issues.
Remember software like Parallels and others install kext files that can break on OS X upgrades, if you get a gray screen, simply hold Shift key and reboot to get into the machine.
Ideally it's best to install Snow Leopard fresh, then upgrade to Lion, then install all programs then user files last, hopefully you won't have to do all that but it is the most reliable method of insuring a pristine system and upgrade free of the unknowns.

Anyone had problems syncing iPod Classic after upgrading to Lion?

I upgraded to Lion over the weekend and eventually got all the associated software updates finalised last night. I tried to sync my iPod, but couldn't. So I reset factory settings, which usually works a trick if there's a problem. That worked - it's now empty. I then set about trying to reload it. No joy. Over the last seven hours, I've had several, conflicting, failure messages, the last being Error 13010. I can't find that error message anywhere. I'm getting a bit upset, and less and less competent. Anyone got any bright ideas?

Perhaps this older thread can help regarding the 13010 error.

Are there benefits of erasing disc before upgrading from Lion to Mavrick?

A friend suggested backing up only my necessary files on my Lion based MBP, wiping the disc clean (erasing), and then installing Maverick. He says it will clean out any old junk and make my MBP run really fast. If true I would like to do that, but would like confirmation and suggestions on best steps to accomplish the feat. Thanks!

Yes. On the off chance your old system is somewhat corrupted a fresh install prevents any of that from corrupting the new system. I recommend it. But, if that is not feasible to do, then be sure you do this before any change:
Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

Before upgrading to Lion

I read some different stories on FCS 3 and Lion. Is it save to upgrade? Or do I loose functionality like my blackmagic intensity card and the voice over tool.
FCP is running on a mac pro 2.66ghz 2009
TIA

First thing is that iCloud isn't working on 10.6.8 and I use mobile.me for storage and sync. Don't want to loose that.
Second thing is that I think Apple will move towards more iApps and functionality in Lion.
But I want to stick with FCP 7 for now. Until it's clear if Apple admits it's mistake with FCP X and supports FCP 7 again (don't think so)
You don't lose Mobile Me by moving to Lion. Syncing is moved to iCloud only if you sign up for it. Storage stays on your MM iDisk. FCP 7 -actually all of FCS 2009, works fine in Lion too.

Listen up people!!! Before upgrading to Lion, make a backup!!!

And not just a TimeMachine backup -- go out and buy an external hard drive (they are cheap) and use Carbon Copy Cloner or Super Duper to make a bootable clone of the disk.

I wish I had done a backup other than TM. Lion is working perfectly on my MBP (2010) except it will not recognize my TM backup on a WD MyBookWorld external drive any longer. I posted elsewhere and had a response that said that Western Digital is aware of the problem and is working on a work around.
Does anyone here know of a fix for this?

How can I make lion to recognize my USB 3.5g ZTE mf626 modem? It worked before upgrade fine.

The modem worked fine before upgrading to LION, now the hardware isn't recognized by the MBP, I unistalled the software and started the installing again, but nothing happened. It simply doesn't work.

Your Mac is probably running in 64-bit mode under Lion while the driver is still 32-bit. You'll need a new 64-bit driver for Lion, which may be an issue depending on the vendor.
See item 2 here:

I've just order a US Robotics USR5637 modem as that's meant to work under Lion—Apple's Apple Modem is no longer supported.

Since upgrading to Lion, iDVD does an unexpected end when I click the burn icon ... ?

I'm trying to burn an iDVD project to a DVD-R disk and each time I click the Burn icon, iDVD goes into an unexpected end and closes. I burned this project numerous times before upgrading to Lion, with no issues. Anyone have any ideas on a solution? I'm running iDVD version 7.1.2 on a MacBook Pro

Thanks again but I have no peripheral devices connected. It's very annoying whenever I close the lid the logo stays lit and the computer does not go to sleep (light on front stays solid white). Each time it happens I have to open and close the lid 3-4 times before it finally goes to sleep. It's as if the computer gets hung up trying to go to sleep.

Upgraded to Lion and Safari won't open. I have completed all available software upgrades, reset the macbook several times, no luck. Any suggestions?

I'm using a 2008 macbook 10.7.4 operating system.
I had purchased lion a while ago but had to wait for a fast internet connection to download and install.
I did that today and now safari won't open.
I have reported the issue as it does automatically.
But obviously I would love to have a solution to the problem.
I do have time machine and completed a back-up just before upgrading to Lion - so if I have to I can reverse back to snow leopard, but that's a last resort.
Any solutions or work-arounds for this? I can't seem to find any other solutions from the blogs.

Before anything else...try...
Quit Safari.
Go to ~/Library/Preferences
Move the com.apple.Safari.plist file from the Preferences folder to the Desktop.
Relaunch Safari. If that helped, move the.plist file to the Trash. If not, move it back to the Preferences folder.

Aperture 3.1.3 won't open after upgrade to Lion

Using latest Aperture 3.1.3 on Mac Mini, 2.53 Core Duo, 4GB. Worked fine before upgrade to Lion last week.
Repaired permissions, deleted com.apple.aperture preferences (in now hidden ~/Library), deleted program and reinstalled as new download from App store.
Error message upon startup says:
Dyld Error Message:
Library not loaded: /Library/Frameworks/PluginManager.framework/Versions/B/PluginManager
Referenced from: /Applications/Aperture.app/Contents/MacOS/Aperture
Reason: no suitable image found. Did find:
/Library/Frameworks/PluginManager.framework/Versions/B/PluginManager: no matching architecture in universal wrapper
BTW - "Option - Cmd" during startup won't get to Aperture repair option.
Maybe I am missing something simple. Anybody have any ideas? Thank you!

Ok - found my own solution after a more thorough search of forums. Tried it and this solved the problem:
https://discussions.apple.com/message/15111356#15111356
(Thanks!!!)
In a nutshell,my guess is that my installing Motion 5 was the culptrit, as there seems to be something that installing Final Cut and /or Motion does to affect the Library structure of Aperture.
The suggested deleting and re-downloading of the plugin manager buried deep in /Library/Frameworks/PluginManager.frameworks/Versions/B/PluginManager did the trick.
Aperture works like it should.

I have a 3rd generation ipod nano. I upgraded to lion. I tried to buy an audio book and download it to my nano like I have done at least 50 times before. Now the dialog box states that I need an ipod touch for the same function. MacBook Pro 2008 w/ m.trac

I have a 3rd generation ipod nano. I recently upgraded to Lion which is causing lots of issues. Aside from that, I went to the Itunes store to purchase books like I have done at least 100 times before with no problems. Now I can by the book and get it to my computer, however when I tried to download the book to my 3rd generation ipod the dialog box informed me that to download any new audiobook purchases I would need an ipod touch. My ipod nano 3rd generation serves my purposes just fine. Why should I be forced to buy something I do not want just to continue something I have always done seamlessly? I know this is more of a rant than a question but I am sure someone else out there has had this happen to them. Maybe you could share your thoughts on how to work around this issue if possible?

I forgot to add the last obvious and crucial step I had taken - plugging a different iPod into my system. It was also not recognized. That was the final proof I needed to determine if the problem was device or system. But now what?
I truly appreciate any help I can get!
Thanks again...

I just upgraded to Lion. I was trying to set up the iCloud and it asked for my "login" keychain password. I've never been asked for that before. I've tried every password I can think of and nothing works. Is there a way to reset the keychain password?

I just upgraded to Lion. I was trying to set up iCloud and it asked for my "login" keychain password. I've never been asked for the keychain password before. I've tried every password I can think of and nothing works. I'm normally asked for the password to my machine when upgrading software, signing on, etc. but this is different apparently. I tried the same password and it didn't work either. I read a couple of posts and they all want to take me through Applications/Utilities but that requires knowing your password in order to change it. I don't know it. Don't remember ever setting up a keychain password. Does anyone know how to change the keychain password if you don't know the keychain password???

Most of the time your Keychain password is the same as your login password. If you configured your computer to log you in automatically, you may not have used your login password in so long you forgot it.
There is no way to retrieve the "login" Keychain password, but you can reset the Keychain from the Preferences menu: select it in the Keychain Access menu and select "Reset My Default Keychain". This will create a new, empty Keychain but the old one will be saved should you ever remember its password.
The result of this is that you will have to supply passwords for everything that requires it, since without your Keychain they will no longer automatically fill themselves. However, once you supply them and store them in your new Keychain, they will be remembered.

When I upgraded my iMac to Lion I can no longer connect the iPad 2 to WiFi. It gives me a message unable to search for WiFi. Before the upgrade to Lion it worked fine. What gives?

When I upgraded my iMac to Lion I can no longer connect the iPad 2 to WiFi. It gives me a message unable to search for WiFi. Before the upgrade to Lion it worked fine. What gives?

Could there be a setting I need to adjust in the iPad2? When I try to turn on WiFi and enter the name of the WiFi that I have established, including the security type and the password, I get the message "Could not scan for wireless networks." Is there a setting in iCloud or other location that needs to be changed?
