Upgrading from 10.6.3 to 10.6.8 stuck in restart

Trying to upgrade iMac from 10.5.8. Installed snow leopard 10.6.3, now trying to install software update to 10.6.8 so I can download Yosemite. Screen stuck in middle of the restart process, just showing purple star page. Is this normal? It's been about half an hour.

Clarify some things for us...
How did you install 10.6.3?
How are you 'installing' the update to 10.6.8?  Apple Menu > Software update?
Were you prompted to restart? at what exact point?
What is the 'middle" exactly? Middle shutting down? Middle starting up?
I can find no reference to 'purple star' at support.apple.com... take a photo with your fone and post?
If this is the middle of a restart, rather than during an install phase, I can see no harm in a Force option - choose from the list in OS X: Keyboard shortcuts - Apple Support
Sleep, shut down, and log out shortcuts
Use these key combinations after your Mac has started up to sleep, shut down, log out of, or restart your computer.

Upgrade from 10.3.9 to tiger and can no longer restart or shutdown

I upgraded my powerbook G4 with 1 gb of ram with tiger recently and ever since, I can not reboot or shutdown without holding down the powerbutton. The system shuts down all programs and then hangs on the desktop with no applications running... just a blank screen.
If I press the powerbutton, the window that prompts you what you want to do (shutdown, restart) comes up, but does not do anything.
I use file vault.
Any ideas? I can not find anything on this on any support site. I can not reinstall the OS again... as I can not restart into the CD or boot from a CD by holding down C.
HELP
I'm about to trash this mac and by a PC!

Since you can't boot from the Tiger install disc to run Disk First Aid repair, you can run FSCK instead with instructions for doing so provided per this link.

After upgrading my operating system, after being on different pages for sometime, i get a shaded that comes down and says i need to restart my computer then tells me to send in error report when it reboots....what do i do

This is called a Kernel panic.
See here for possible solutions:

Did you do anything else apart from ungrading OS?
Did you add memory?
Bad or not well seated memory modules are often a cause of kernel panic

IPod Help needed from serious Apple gurus - iPod Touch 2g 16g stuck in restart loop. Will NOT enter DFU or recovery mode, NOT recognized by iTunes on Windows or Mac

Ok, so here's the not so sad story. I bought an iPod Touch 2g 16g through Ebay - so forget warranties. Luckily I did not pay much. The description said it was stuck on the apple logo, so I figured it would be an easy put into recovery mode and restore problem.
Not so much.
If you plug the iPod in and charge up the battery the LCD will come to life after a while with the apple logo, then it displays the spinning wheel with the apple logo over it. That will last anywhere from 10 - 15 minutes, then the iPod will go blank for a few secs and then start up the cycle all over again.
As stated, this iPod will NOT enter either DFU or recovery mode and believe me I've tried it several times several different ways with different timings, connected via USB to a Mac, connected to a different Mac running Windows, and connected to just the charger. Nothing. Occasionally the screen might go blank while holding the power and home buttons but nothing else happens and then it starts it's usual cycle again.
Again, iPod NOT recognized by iTunes on either Mac or Windows side. Since I got off Ebay and seller didn't know much about it, I have no idea if someone tried to jailbreak this or not.
I will not put much money into this machine. So I guess my question is: does this behavior mean that the motherboard is clearly fried? Are there any software programs that might diagnose what the problem is? Could it be as simple as a fried battery?
And most importantly, is this iPod simply toast or is there anything anyone can suggest????
Really any suggestions would be greatly greatly appreciated. Seems a shame to just trash an iPod touch that might need a simple fix...
If it helps matters, I can tinker with iPods somewhat and have torn down and replaced several iPod touch 1g and 2g glass and digitizers with no problems. I'm somewhat software savvy but the whole jailbreak thing is new territory... and I can't really figure out the command in Windows or Mac terminals to list all connected devices so I have no idea if the computer even knows the iPod is there, even if iTunes doesn't. Guess that's it... ummm, please help???

Nothing huh? No one's had this problem or this isn't fixable... oh well... if anybody comes up with anything I'll check in occasionally...

Is it really possible to upgrade from a Treo 650 to a Treo 750?

I am not a very happy customer at the moment, but any help would be greatly appreciated. I upgraded from my old Palm Tungsten to a Zire, then to a Cingular Treo 650, combining three devices into one. I have since discovered that the Treo 650 seems to have a faulty transmission mode, as I can rarely be clearly understood by whomever I call. Am on the second (or third, I have lost track) and continue to have the same problem. I get five bars of reception but can't be understood on the other end. A bit of a problem when one is trying to call 911. Am constantly told I am "breaking up". The repair shop says it "Can't duplicate the problem". OK, then I do not want to give up all the info I have stored in the fool thing, and the 750 seems to have a different system, so I thought I would try that. All the stuff I could find seemed to indicate it wouldn't be a problem to upgrade. When the 750 arrived, I tried to install the software from the CD on my Windows XP computer. No dice. Setup encounters an error and closes. Can't even look at the files, because setup tries to run any time I access the CD. From any drive. Gave it to my girlfiend to check on her computer, and the CD seemed to run fine. Other CDs work just fine on my computer. Must be some kind of conflict, but what? Tried calling the AT&T number that suggested they could help with setup, and was first connected to the business center, they routed me to the laptop center, who routed me to the network center, who said they would have to bring in the Palm customer service and connected me to a Mac guy that dumped me back to a menu that took me to someone for whom English is a second language with whom I was trying to communicate over a very poor satellite connection. They made no sense anyway. telling me first that I couldn't have two desktops running (wrong, my girlfriend has my old Zire and the CD worked fine) and then insisting that the serial number on my device had to start with a P, when it clearly does not have any alpha characters in it. Gave up on that route of assistance. Managed to get the new ActiveSync installed from my girlfriends computer over the network. Great. Now let's get my 650 synced with Outlook (which I have not used at home) and see if we can move on. Nope. First I have to update Outlook 2000 from the old Win98 to my current XP. Find the old CD, and square that away. OK, now sync to Outlook. Nope. The sync program gives an error, saying it will only sync with Outlook 98, 2000, and XP(2002). Good grief. I have Outlook 2000, and the software apparently does not recognize it. If the Palm doesn't work, there is no reason for me to keep this phone, and I am very close to returning it and abandoning the Palm entirely when I upgrade to something that works, although I dread re-entering all that information.

Thanks for the feedback. Today I installed an Enterprise version of Office 2007 I purchased a while back, but had not yet installed. Microsoft presented a few challenges, but they were quickly resolved. I then downloaded the appropriate conduit from Palm, and synced the 650 with the handheld overwriting the computer. Then used Active Destop to sync the 750. Satisfied I had moved as much info as possible, I called AT&T and had them move the phone number to the new Treo.
Bonus! When the guy at AT&T called me on the new phone to verify it, he said it sounded better than my landline.
Sorry for the streaming paragraph. When it is late I tend to write like I think.

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine until I deleted an app in error. When I downloaded it from iTunes, my account is no longer recognized by the app's host servers. Can I go back and re-sync one app from my old phone?

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine. Yesterday I deleted an app in error. When I downloaded the software it from iTunes ( did this many times on the old 3GS), my account is no longer recognized by the app's host servers (Playtika), even though it did after the initial conversion. Can I go back and re-sync just one app from my old phone?

Try deleting what is called the iPod Photo Cache.

Can't print from IE 8 after upgrading from Vista to Windows 7

My laptop (HP Elitebook 8530w) uses two HP printers: Color LaserJet CP3525x (at work) and Deskjet 6940 (at home). Both printers are accessed across a local network.
I recently upgraded from Vista Enterprise to Windows 7 Enterprise.
Everything still prints fine (from Word, Adobe Reader, Windows Photo Viewer, etc.), except for IE 8! When I try to print a web page from IE, it prints only the page header, and otherwise the sheet is empty. This symptom occurs on both printers. (And of course this worked fine before the upgrade.)
Any ideas? Thanks for any help.

If anyone else is having this problem, I found the solution on another forum (http://social.answers.microsoft.com/Forums/en-US/InternetExplorer/thread/920588e5-ccc4-4e24-83d6-606...).
Specifically, the following steps solved the problem:
1. If it doesn't already exist, create a directory named "Low" in your directory "C:\Users\<your_user_name>\AppData\Local\Temp\".
2. From a command prompt, issue this command: ICACLS C:\Users\<your_user_name>\AppData\Local\Temp\Low /setintegritylevel (OI)(CI)low

Fields in read-only mode for BP transaction in upgrade from 4.72 to ECC6.0

Hello,
This is regarding the query for BP transaction in upgrade from 4.72 to ECC 6.0.
While creating BP / Changing BP system is disabling the fields in compnay code & sales area option. There is a SAP not provided 907860; and specified that the proplem is because of the delta customizing.
All the customization settings are as per the note. And the Synchronization Control is also activated. But still the fields are disabled only.
I have checked the field settings also in Cross-Application-Components & Logistic-Genral.
But these are not working for compnay code & sales area data.
please let me know if anyone has faced this type of problem / found any solution on this.
Best Regards,
Shubhada

SAP IMG -> Cross Application Components -> Master Data Synchronization  Synchronization Control -> Synchronization Control -> Activate Synchronization options
This setting allows you to activate synchronization of BP with R/3. Not maintaining the values may result in certain fields being read-only in BP.
Suggested Values:
Source Object: BP | Target Object: CUSTOMER | Active Indicator : X
Source Object: BP | Target Object: VENDOR | Active Indicator : X
Source Object: CUSTOMER | Target Object: BP | Active Indicator : X
Source Object: VENDOR | Target Object: BP | Active Indicator : X
Have you set all of the above settings??

Slow table creation after upgrade from 10.2.0.3 to 11.2.0.1 using DBUA

I've recently completed a database upgrade from 10.2.0.3 to 11.2.0.1 using the DBUA.
I've since encountered a slowdown when running a script which drops and recreates a series of ~250 tables. The script normally runs in around 19 seconds. After the upgrade, the script requires ~2 minutes to run.
By chance has anyone encountered something similar?
The problem may be related to the behavior of an "after CREATE on schema" trigger which grants select privileges to a role through the use of a dbms_job call; between 10g and the database that was upgraded from 10G to 11g. Currently researching this angle.
I will be using the following table creation DDL for this abbreviated test case:
create table ALLIANCE (
   ALLIANCEID           NUMBER(10)                      not null,
   NAME                 VARCHAR2(40)                    not null,
   CREATION_DATE        DATE,
   constraint PK_ALLIANCE primary key (ALLIANCEID)

Below I've included data on two separate test runs. The first is on the upgraded database and includes optimizer parameters and an abbreviated TKPROF. I've also, included the offending sys generate SQL which is not issued when the same test is run on a 10g environment that has been set up with a similar test case. The 10g test run's TKPROF is also included below.
The version of the database is 11.2.0.1.
These are the parameters relevant to the optimizer for the test run on the upgraded 11g SID:

So while this certainly isn't the most elegant of solutions, and most assuredly isn't in the realm of supported by Oracle...
I've used the DBMS_IJOB.DROP_USER_JOBS('username'); package to remove the 194558 orphaned job entries from the job$ table. Don't ask, I've no clue how they all got there; but I've prepared some evil looks to unleash upon certain developers tomorrow morning.
Not being able to reorganize the JOB$ table to free the now wasted ~67MB of space I've opted to create a new index on the JOB$ table to sidestep the full table scan.
CREATE INDEX SYS.JOB_F1_THIS_NEXT ON SYS.JOB$ (FIELD1, THIS_DATE, NEXT_DATE) TABLESPACE SYSTEM;The next option would be to try to find a way to grant the select privilege to the role without using the aforementioned "after CREATE on schema" trigger and dbms_job call. This method was adopted to cover situations in which a developer manually added a table directly to the database rather than using the provided scripts to recreate their test environment.
I assume that the following quote from the 11gR2 documentation is mistaken, and there is no such beast as "create or replace table" in 11g:

"Dropping a table invalidates dependent objects and removes object privileges on the table. If you want to re-create the table, then you must regrant object privileges on the table, re-create the indexes, integrity constraints, and triggers for the table, and respecify its storage parameters. Truncating and replacing have none of these effects. Therefore, removing rows with the TRUNCATE statement or replacing the table with a *CREATE OR REPLACE TABLE* statement can be more efficient than dropping and re-creating a table."

Since upgrade from Exchange 2007 to Exchange 2013 the conversations in Outlook do not group by subject

Hi Microsoft,
Since we have upgraded from Exchange 2007 to 2013 users complain their conversations in Outlook are no longer grouped based on the subject of an e-mail. I looks like Outlook uses other message properties for grouping e-mails in a conversation.
I have investigated all the forum topics and see that with exchange 2010 there is support added for the use of conversation-ID's. However the functionality to automatically group e-mails with the same subject in one conversation in Outlook is gone!
I would like to know if there is a fix to implement so that some our users get this functionality back. For Example: Let the exchange server not generate conversation-ID's and message-ID's for certain users.
Your help is greatly appreciated!

Totally correct!
If you don't plan to maintain Outlook then you plan to fail :(
