Removed Wheel group from Macintosh HD... Macbook stopped responding

I have been setting up a large sharing network with my housemates and have been messing around with sharing permissions quite a bit. I saw a group named wheel and foolishly removed it from somewhere... I think it was the Macintosh HD... the Macbook stopped!
Upon researching, I now know what the wheel group is, and that I should have left it the **** alone. At the time though, I thought it was someone in the house with access to my whole drive.
I have tried repairing permissions in disc utility, but still get spinning wheel (ironic) upon restart.
DO I need to re-install OSX?
The macbook pro came with snow-leopard and I upgraded to lion, if I re-install from 10.6 disk will I have issues?
Is there another way?
Any advice would be greatly appreciated....
And I know, I shouldn't have been messing with things I don't understand.
Cheers

You should be able to reinstall lion from it's recovery partition.

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

It's almost impossible. The new iMacs have a Target Display Mode, but it's built to do that. Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15. In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
By the way, I found your answer by searching this forum. I would suggest using the search function here in the futuere.

How do I remove old applications from my new Macbook Pro that came over when the data on my iMac was migrated to the new computer.

How do I remove old applications from my new Macbook Pro that were part of the data that was migrated over from my older iMac?
Thanks

If the applications were originally drag and drop installations you can simply drag them to the trash and empty. If they were installed by an installer there should be an uninstaller included. If you're not sure you should check with the software developer for instructions. In this case Google can be your friend.

How can I remove 300 groups from my iCloud Contacts?

My OS X Address Book started out with about 10 groups, but now iCloud.com has about 300 groups.
The replication arose because of a bug in how iCloud handles a mixture of Address Book Cards with both OS X and Windows line terminated Notes (LF vs. CRLF - it helps if you once used a typewriter).
I figured out how to convert Address Book to all LF terminated line feeds and I was able to get iCloud.com working on a different account, but my core account is stuck with 300 groups (some replicated 50 times).
I know how to delete all Cards/Contacts in iCloud.com Contacts, but, unfortunately that doesn't remove Groups. (Groups have an interesting behavior in iCloud, almost as though Apple has a special plan for them.)
I can delete Groups one at a time on iCloud.com, but that's tedious. Unfortunately deleting them on Address Book, and trusting in sync to clear up iCloud.com, is equally tedious.
Has anyone heard of a way to delete all Groups on iCloud or Address Book 6? Perhaps an AppleScript?
Has anyone heard of Apple resetting a corrupt iCloud account to clear out bad data? (I have a clean version of Address Book I can use to restart -- that, by the way, is harder than you'd think. Again because Groups are special).
Advice appreciated. If I get some free time I might take may laptop by the Genius bar and see what they say...

I figured this out. In this case I didn't care about my Contacts, I had them elsewhere. My problem was my iCloud acount was "poisoned" with massive replication of 'Groups'. Even after I deleted all the Contacts I still had hundreds of Groups to get rid of. Manual deletion was too tedious.
The answer was a simple AppleScript (I'm on ML on the machine i ran this on, so it's "contacts" rather than Address Book:
tell application "Contacts"
          repeat 50 times
                    set theGroup to group "MyGroupName"
delete theGroup
          end repeat
save
end tell
Since I had the same Group Names replicated about 100 times each, I only had to run this about 10 times to clear them all out. When I got to smaller numbers I had to drop the repeat count. I changed the Group name as I went.
Took me about five minutes.
I'm sure an AppleScripter could turn this into a general script for removing all groups all at once. Or could get very clever, and only remove groups that had no contacts (so one could salvage the group/contact relationships).
I didn't need that. My problem has been fixed.
I think sync works a LOT better in ML than Lion btw. iCloud updated very quickly.

Removing Proxy Settings from a Networked Macbook

Help needed.
Since updating my operating system (10.8.2), I have been unable to access the internet at home. Whenever I try to open a page the message appears saying that it has been unable to contact the proxy server. However, I have already removed the ticks from use proxy for http and https and I have tried to set up two locations one work where proxy settings are needed and home where they are not. Nonetheless, when I try to access the internet the same proxy message is returned.
Any advice greatfully received.

CRIO disconnects from Ethernet network and stops responding to pings

We are running a cRIO application that periodically disconnects from the Ethernet network even though the VI continues to run on the cRIO.
The application has two parallel loops. One loop reads data from the FPGA and writes it to a RT FIFO. The second loop opens a TCP connection to a remote host, reads data from the RT FIFO, and transmits the data to the remote host. We have instrumented each loop to send messages to the serial port that indicate their status. When the cRIO disconnects, both loops continue to send their status messages to the serial port. The first loop happily continues reading data from the FPGA and writing it into the RT FIFO. The RT FIFO overwrites the oldest data when it fills up to keep it from overflowing. The second loop reports a TCP write timeout (tcp write error 56) around the time that the cRIO disconnects, after which it closes the existing TCP connection and then repeatedly tries to open a new TCP connection (each attempt times out after a 5 second delay).
All that appears normal and usually the connection is automatically restored. Occasionally, however, the cRIO is not able to re-open the TCP connection. Furthermore, the cRIO stops responding to pings from the remote host. On two occasions, the cRIO was finally able to open a new connection after 30-40 minutes. Other than that, the only way we've found out of this dilemma is to reboot the cRIO.
The frequency of the disconnects and the time before they occur doesn't seem connected to whether or not the cRIO is set to run the application at startup or if the application is run via an interactive VI window on the remote computer.
It is possible that the disconnects have something to do with which computer the cRIO is connected to, as the problems seem to happen much more frequently (often within minutes) when the cRIO is sending data to a laptop running Windows XP, but it can run for hours when sending data to a rackmount server running Windows Server 2003. Everything else (the speed and size of data being sent, the ethernet hub and cables, the VI running on the remote computer) is the same.

We're done most of the testing with a 9014 real time controller and a 9104 chassis. However, we've also seen similar behavior with 9014/9103 and 9102/9101 combinations.
The 9014 cRIO normally runs at around 50% CPU usage and less than 40% memory usage when the data is flowing steadily. The RT System Monitor did not indicate a spike in either before the cRIO disconnected.
Measurement and Automation Explorer is not able to connect to the cRIO after it disconnects. We tried pinging the cRIO from a different computer, but that also failed.
After disconnecting, the cRIO sends error messages to the serial port while trying to open a new TCP connection. It reports an error 56 (time-out error) 3 or 4 times (for a total duration of 15 or 20 seconds) and then reports an error 42 (generic error) at least 10 times per second for 18 seconds, and then switches back to 15 seconds of timeouts, and so on. When getting error 42, it ALWAYS gets it for 18 seconds straight. It usually gets error 56 for 15 seconds (3 timeouts) but sometimes for 20 seconds (4 timeouts).
When the cRIO disconnects, it can't be contacted by any computer through the ethernet port, yet the link lights still show that it is connected. If its connected directly, both the green and orange link lights on the cRIO light up, but when it is connected through the 10 Mb hub, only the orange link light lights up, but the hub shows that the cRIO is connected to it. In spite of this, it is still impossible to ping the cRIO in either scenario.
It is possible that, in addition to what computer the cRIO is connected to, the errors could be related to whether the cRIO has a direct connection to a computer or if it is connected through a hub. Today, we have only managed to get errors when the cRIO is directly connected to a laptop (one error after 1.5 minutes, one after 10 minutes, one after 7 minutes, etc.) There were no disconnects when the cRIO was connected to a 10 Mbps hub for more than half an hour.
Do any of those symptoms give you clues about what is happening?
Thanks!

New C2D Macbook, Stops responding in Itunes

Hi
I have a new Core 2 Duo Macbook that stops repsonding when importing cds into Itunes. It will hang up on a track and the superdrive keeps spinning. All I could to was restart the computer to recover. I have not had the same problem with my Macbook Pro C2D.
Is the Superdrive extremely sensitive to minor scratches, dust, etc? Or is importing a large amount of cds in a row a bad idea?

It shouldn't be a problem to import a lot of cd in a row.
The problem could be the cd is scratch, and yes, the macbook optical drive might be a bit extra sensitive for scratched cd.
If you have external optical, use that one for "problem" cd.
Good Luck.

Could not add/remove Groups from User in UME

Hi All,
I am ABAP + Java stacks.
There is a user ABC with an ABAP role ZZZ which is displayed as a group in UME console.
When I tried to remove this Group from this user in UME, system returned error message:
You are not authorized to assign one or more entities. Perform a new assigned entities search to see the correct status.
Even I add a new Group to this user is forbidden.
But if I delete this Role in ABAP SU01, it synchronize disappeared from UME quickly.
I don't know why. it seems does not relevant to authorization problem since I already have full auth.
Could anyone help me?
Thank you so much.
Best regards,
Nick

Hi Nick,
You can never assign abap role from portal. You can only map the portal role to abap role.
when you create group on portal , it will not be refelect as an role in abap system. becauase when you create a group it will create as basic group with identity as private database and not as R3.DB.
If you want to confirm , then create and group and save it , after saving it check what is a UNIQUE ID.
Thanks
Anil

How to delete / remove a group in AD using LDAP?

Can anyone please point me in the right direction to code the ability to delete or remove a group from AD using LDAP? Is this even possible? I'm surprised I cannot find anything related to this action.

How would you delete any other object using LDAP ?
Why do you think deleting a group is any different ?
String groupName = "CN=Idiots,OU=Developers,DC=Antipodes,DC=Com";
// Create the initial directory context
LdapContext ctx = new InitialLdapContext(env,null);
// Delete the group, and wishfully all the idiots that ask stupid questions
ctx.destroySubcontext(groupName);

Provisionusers.cmd and Migrate users/groups from Planningweb

Hi
Is the functionality of Provisionusers.cmd and migrateusers/groups from planning web similar?
I feel Provsionsuers.cmd is an alternative way to migrateusers/groups from planning web.
Please correct me if i am wrong.
Thanks and regards
krishnatilak

Hi,
The provisionusers utility basically syncs planning and essbase with the provisioning of users/groups in shared services.
If you run the utility and a user exists in shared services but has not been created in the planning database the user will be added.
If the user does not exist in the essbase security file then they are added.
If it is a user that exists and has security settings on members in planning then these filters are pushed down to essbase.
It should also remove users/groups from planning if they have been deprovisioned in shared services.
Cheers

Way to unload FM group from memory

hi experts,
Is there any way to remove fm group from memory and reload it into memory mannual in the components of the fm group?
I set up a workflow and create a fm group to work for the workflow. A task in workflow calls a BO's method which calls a fm of the FMgroup for a user dialog. The user dialog screen belongs to the same fm group.
But I found in business workplace(SBWP), when the previous workitem completed , that is, the user finish his screen, the FMgroup is not removed from memory. I think it is because the calling program, the business workplace, didn't end. So I wonder is there any way to remove the fm group from memory mannaully?
thx!

In Java who unload objects of memory is the Garbaga Collection.
But we can help the G.C. doing the object eligible to be unload. For example.:
class InfoData{
class A{
public static InfoData id = new InfoData();
... do something with id ...
public void aMethod(){
id = null; //do the static object elgible to be collected by G.C. !!!
}

Removing LDAP group

Hi,
i've got a little problem witch i cant handle, after hours spent on searching the web i decided to ask here for help.
SAP BO 4.1 sp4 installation.
One day one of administrators configured LDAP, and created some groups from that ldap (it was his private LDAP, standing under his desk). The LDAP is now disabled and its configuration is unknown.
How to remove that groups from BO? (when group is clicked with right button there is no option to 'DELETE' - its not even gray, there is no such option).

You can follow setps from KB:http://service.sap.com/sap/support/notes/1186759
I would recommend you to use this as your last resort and after you have backed up your server
Steps to follow:
1) Run steps from KB 118679 to unregister the secLDAP.dll
2) See if it allows you to delete groups now else try hitting the update button in LDAP configuration page (where you map groups) and see if it deletes the mapped groups.
3) If it works : re-register the secLDAP.dll using Regsvr32 secldap.dll in cmd. (same steps as in the KB but without /u)
Let me know if it helps
