Can you run Tiger and OS 8.6 on the same computer? RE: Repair Permissions

Hello,
I don't fully understand how "Repair Permissions" work and when it is needed and therefore I would like to post this question for some clarification. Using "Repair Permissions" for troubleshooting is a controversial issue. I read this interesting opinion about Repairing Permissions and now I am concerned that it may not be safe for me to install my old OS 8.6 on my OSX installed computer due to a "permission" conflict between OS 8 and OS X.
Could someone confirm this with me please? Could this cause some file permission problems?
I would use OS 8.6 to run my older Adobe Illustrator 8 application and photoshop 6. And then I will boot onto Tiger for everything else. I would switch a few times per day back and forth.
Basically, is it safe to run Tiger on the same computer that has OS 8.6 installed on it? (I am not concerned about making 8.6 run in the Classic environment because I know that doesn't work - I am refering to having separate bootable installs)
[1] http://www.unsanity.org/archives/000410.php
PS I am aware of how to change my startup OS on this particular computer (b&w G3). I would have to have the two OSs on the same volume and launch X by pressing x -key during startup due to the fact that OS 8.6 doesn't have the Startup Disk feature introduced in OS 9. That was an earlier separate discussion that has since been solved.
PS
I could choose to instead use my OS 9.2 but I have reserved that OS for another computer unfortunately. However depending on the outcome of this post, I might have to reconsider.

This is a really difficult issue to resolve! Apple doesn't have much documentation that covers running OS 8 & OS X on the same drive. There are, however, a few things that it might helpful to know:
1. Repairing permissions with Disk Utility in OS X won't touch user-created files. It only repairs things that have a receipt file, which are created by installers. The unsanity reference explains this; you might want to review that part of the article again.
2. Disk Utility has a separate repair OS 9 permissions function (accessed in the menus), but AFAIK, this only repairs permissions on the OS 9 system folder "blessed" by the Classic system pref as the one to use for Classic. I doubt this would be useful for the OS 8.6 system.
3. Of greater concern than mis-set permissions is file system damage. Under no circumstances should you use any disk repair utility on a Tiger drive except those that "know" about Tiger's file structure. This rules out using Disk First Aid from either OS 8 or OS 9, or any OS 8 or 9 third party utilities. (See this Apple document for the details.) I don't know if this also applies to OS 8's 'rebuild desktop' function, but I would avoid it to be on the safe side.
4. If you do decide to reformat or partition your drive for dual booting (as you mentioned in your other thread), do so only with Tiger's Disk Utility & remember to check the 'install OS 9 drivers' option or you won't be able to boot into OS 8 or 9, even if you have a viable system folder for either on the drive. See this Apple document for more info.
5. In light of the above, it is well worth getting OS 9 to use with Tiger on your B&W, as long as any older apps you need to run are compatible with it. (There should be no need to use OS 8/9 with text files anyway, since OS X can handle all the old text formats.) In fact, unless you need to use some peripheral that has no OS X driver, you probably will do just fine by using Classic with the old apps, eliminating the need to reboot completely.
6. If you need to buy OS 9, one inexpensive source is OWC's Mac OS 9.1 - OEM CD. At $35, it is a cheap way to avoid the headaches of OS 8 with Tiger! Note that you can upgrade from this 9.1 version to 9.2.2 for free with Apple's updates available from the Mac OS 9: Available Updates web page.

Can you run 3G and connect to wifi at the same time?

Is it possible to use the iPhone 5 to search 3G and connect to wifi at the same time? I'm trying to run my Apple TV but only have 3G that is run through my phone. I want to play Netflix using Apple TV run from 3G through my phone.

The phone and the ATV need to be on the same wireless network. You cannot communicate with the ATV using 3G on the phone

How can you add a 2nd i Tunes account on the same computer?

How can you add a 2nd i Tunes account to the same computer?

I had an application where I spawned (= ran with Start Asynchronous Call) multiple (reentrant) copies of VIs, and would occasionally "lose control" of them. I needed a way to find all VIs that were running "Top Level" and stop them (so I didn't have to log off from Windows).
I used the Application Property "All VIs in Memory" to get an array of (wait for it ...) All VIs in Memory. I took each name, opened a VI reference to it (simply wire the name string in, as the VI is, by definition, "in memory"), looked at its VI Execution State, and if it was Run Top Level, Invoked the FP.Close and Abort VI Methods. [To prevent the VI that did all this from "committing Suicide", I compared the name string with the current Call Chain, and did nothing if there was a match].
I think you could adopt this idea to do what you need.

Can I run 2 different updates of FCPX on the same computer?

How can I run 2 versions of FCPX (update 10.1.1 and the original FCPX) on the same computer?
I'm working on a team using FCPX. Recently, my computer updated FCPX to 10.1.1 (I'm assuming bc I have a newer computer & OS). The others on the team have FCPX, the earlier version.
Because we have projects edited on both version of FCP and we need to be able to transfer projects from one computer to another, I need to be using the earlier version of FCPX. However, I also need to be able to edit the 10-15 projects we've started in 10.1.1. So, I'm looking to somehow run the 2 different versions of FCPX on a single computer.
How could I best accomplish this - thru different users? partitioning the drive? Any suggestions??

You also want to make sure that if 10.1 sees your 10.0.9 projects and events that you don't let it update them.

It should work fine. Both my Microphoto's work connected on XP Pro at the same time, I just have to keep track of which one has what kind of music. Have you tried scanning for plug and play devices, what kind of operating sys are you running? And what software are you trying to sync with.

Can't run Pshop and another adobe program at the same time

Hi all,
I'm experiencing a frustration problem. I can't run two adobe programs a the same time - ie, Lightroom and photoshop, After effects and photoshop.
Lightrrom and After effects sem to be playing together okay at the moment so looks like it may be a PShop issue.
Running final release of windows 7 64 bit, licenced PS3, trial AE, trial PS4....8GB Ram, has been with both Nvidia and ATI video cards, open GL on , Open GL off, seperate scratch disks, reinstalled everything,
Any help, advice, hints would be really appreciated as having to close programs all the time when switching apps is a real pain in the neck
cheers
Jeff

thanks whytefly,
yeah I thought that may be the case but then realised both After effects and CS3 are 32bit (86x) and I can't run those together
I'm jealous as hell that you can run 3 together haha,
cheers

Can you have Firefox and IE browsers both at the same time and if so, do you have the choice of choosing one for a default browser?

I am using IE Explorer now presently. I want to be able to download and install the SEO Blogger tool from Wordtracker but it says that I have to have Firefox as the browser. Since I have everything else already set up under IE, I don't want to have to change all that just so I can download one program.
Can you help?
Thanks,
David Craig

You can have both browsers installed and running at the same time. You can also choose what one to have as the default browser.

HT5622 Can you use more than one apple ID on the same computer? I can't sign in and out and sync my iPod because my library isn't on there.

My sister has an iTunes account on our main computer, and I have one on our laptop. I want to be able to sync my iPod with the main computer, but I can't because my library is on the laptop. Is there any way to sync my iPod with my library on the computer?

Yes
http://www.imore.com/how-use-multiple-apple-ids-one-computer-and-itunes
However you can only sync all media from one iTunes library/computer. However, one can sync music and videos with different computers/libraries if you have iTunes setup to manually sync. See that method included here:

Can you have more than one iTunes account on the same computer?

My wife just got a nano and wants to set up her itunes library. Since we have different tastes in music, I thought we should have separate libraries under our separate log-ins to our PC so that her music didn't upload to my iPod and vice versa. Is that the right approach or is there a better way?

There are basically two ways of using multiple iPods on a computer and these involve:
a) Sharing a single iTunes library and user account.
b) Creating multiple user accounts and having separate libraries.
Sharing a Library
If you want to share the one library, you can set either or all of the iPods so that they only get updated with only certain playlists (you can update from more than one if you wish):
Loading songs onto iPod automatically - Windows
Choosing the update option "Sync Music - Selected playlists" allows you to create a playlist specifically for the iPod and drag the tracks you want into it. If you tire of the list and want to change it, you just add or remove the songs you don't want. The ones you take out out remain in the library to be used some other time if you choose. You can read more about playlists at these links:
iTunes: Creating playlists of your favorite songs
How to create a Smart Playlist with iTunes
Or you can choose to update any or all of the iPods manually and just drag whatever content you want to them: Managing content manually on iPod
Separate User Accounts
Another option is to create a separate User account for each person on your PC or Mac. Different accounts by definition would give you completely separate libraries. Each account has it's own iTunes folder, Library and iTunes Music folder and you load it with CDs etc just as you did with your original one. The iPod can be set to update however the owner chooses, sync all, manual or sync specific playlists

Can you run CRXIR1 and CRXIR2 on the same machine?

I have CR XI R1 Developer edition installed on a workstation which I use to maintain imbedded reports in a large system written in VC++ V6, as well as several newer applications written in VB2003. The IT department issued me a new machine on which is installed VB2005. Now I receive errors in my VB applications when using the ExportToDisk function.
I understand that I need to upgrade to CR XI R2 to be compatible with VB2005. How will that affect my older code written in VC++ V6?

Well, you don't really need CR XI r2 to be compatible with .NET 2005 as .NET 2005 ships with CR 10.2. Now, if you want to be at CR XI with the COM apps (VB and C++) as well as .NET 2005, then you do need CR XI r2. (CR XI does not have assemblies for the 2.0 framework)
Personally, I would not recommend CR XI r1 and CR XI r2 on the same computer. Theoretically this should be OK, but from experience, I find that occasionally CR XI r1 and CR XI r2 just don't like to play together...
I'm not sure where you want to go with this now; resolve the export error, then move on, or?

Can you transfer files between two user accounts on the same macbook pro?

Can you transfer files between two user accounts on the same MacBook Pro?
Specifically, I used the Migration Assistant to move music and photos from my old PC to my new MacBook.
Somehow, I missed the fact that it was creating a new user account when it was doing this. So none of music and photos are in the user account I originally set-up. Instead, all these files are now in a different account.
I'd like to consolidate all my files on the one user account and delete the other one.
Is this possible and, if so, how do I do it?
Thank you.

you can crop files from one account to another using the Public Dropbox which every user account has. Log into the user that has the files you want to move, then drag the folder you want to the new users' dropbox:
I suggest a small scale test on a few files first before moving gigabytes of files.

Can you have more than one apple id under the same account

can you have more than one apple id under the same account

Stop using the same Apple ID for iMessage on these devices. Go to Settings>Messages>Send & Receive (Receive At in iOS 5), tap the ID shown, sign out, then sign back in using a unique ID for each device. (Or, just sign out and stop using your Apple ID for iMessage.)

Can you pass multiple files to Business Catalyst at the same time?

I need to pass information from a client. The infromation is split into several files. I can not access the files to combine them to send as one document to BC. Can I send the two files over even though they do not full fill the necessity of all the user information. File 1 is the personal information and has no other details. When this fill crosses over BC accepts with no trouble. When the second file goes across the personal information is not there but the form details are and this file wipesout the DB. Going through debug when the first file executes I see the data on the BC side. When the second file executes the data is all gone. I cannot combine both files to create one document. Files do not have the same number of users so import of file with file helper would not work since it needs to meet certain requirements to process correctly everytime. By combining the two files would give a different number of tabs than what file helper is looking for and by that matter the data may not be in the correct order. Retrieving the data from the file also would not work since I would have to retrieve from both files at the same time and there would be issues if the user does not occur on both files.
Please help.
Thank you,
Carlos

To save time with videos that are not critical, can you capture one video to Premiere Pro at the same time you are authoring to Encore a previously captured video?
The short answer is yes.
I have just done that and I am happy to report that it worked like a charm.
I captured from a DVCAM tape via firewire using PPro CS6 while authoring a Blu-ray disk in Encore CS6.
No frames were lost during capture and my test blu-ray project was completed without a hitch.
