Target SNR moved from 6.0dB to 9.0dB due to a one-...

Last night there was some very strange interference that was causing TV signal issues, radio issues and affected the ADSL line stability. I can't see how many times I reconnected but actually it doesn't look like many at all. CRC errors are low and interleaving is off (which needs to stay off for gaming).
However, as a result, my target SNR has moved to 9.0dB.
The interference has now gone. I tried calling for help, went through to India. They gave me some explanation that my line was "being monitored" and if it was stable they will switch it back to 6.0dB in about 24 hours. Somehow I don't believe anyone is actually watching my line and I will probably be stuck at 9.0dB unless some intervenes.
Any ideas how I actually get this sorted out?
Thanks,
Jonathan

Thanks for the replies!
I have no problem waiting for 3-5 days and I will resist the temptation to reboot the hub in the meantime!
The difference means I lose the top 1 meg of throughput. So its not a huge hit, but, like many, I want the fastest I can have as I download a lot.

Line target SNR gone from 6 to 9 to 12 and now 15d...

Having connected reliably and almost constantly at 7616 (target SNR 6db) and stayed good for the best part of a year my line is playing up again.
Its gradually stepped from 6db through to 15db over the last two weeks and of course the speed and IP profile are going down the pan too.
I've checked all the usual stuff in the house and tried a substitute router all to no avail.
Now the last time we had this problem it took nearly 2 years to convince BT that it was actually a fault on the line and not the line length! They did eventually fix it (old corroded connectors in a green box) when a mod here forwarded my posts to the 'twitter team'
Is there any chance you could do that again please?
Thanks

Thanks
OK here they are:
You will see that the IP profile hasn't dropped to 4000 yet as the target SNR only went to 15db and the connection speed to 4864 this morning, but when it does the throughput will of course be even slower at about 3700.
Checking my router stats light log I see that it all started to deteriorate on the 30th of May.

I just moved from a G5 PowerMac to a Mac Pro with one drive running Yosemite and one running Snow Leopard, Do I need Lion to be able to upgrade iPhotos

How can I see my iPhotos from a G5 PowerMac on a MacPro running Yosemite and Snow Leopard? Is Lion a more advance system that Snow Leopard?

The last iPhoto version you can run with Snow Leopard is iPhoto 9.2.4, and Yosemite needs iPhoto 9.6.
Move your photos to your Yosemite partition, if you want to use iPhoto with Photo Streams and other iCloud features.
As you are asking about Lion, you can run iPhoto iPhoto 9.2.3 or iPhoto 9.2.4 both with Lion and SnowLeopard, but there is no iPhoto version, that runs both on Yosemite and Snow Leopard, or Lion and Yosemite.

Time machine backup files disappeared after moving from Osx 10.6 to 10.8.2 .

I had moved from a 6+ year old iMac to a new one with 10.8.2

Welcome to the Apple Support Communities
I don't think that they have disappeared. They are just "hidden" in your Time Machine drive because Time Machine detects your old backups as for a different Mac than the one you are using right now.
In order to see your old Time Machine backups, read > http://pondini.org/TM/E3.html

How do I remove the target-like images from my pdf?

How do I remove the target-like images from my pdf? There are four of them, one in the very top center, very bottom center, far left center, and far right center.

Are you saying they haven't always been there? If they have been, they're likely registration marks.

Default Target SNR Margin

I was wondering if I could request that the MODS can arrange for my default SNR margin to be decreased back to the default 6dB. After their help via this forum at the beginning of the year I have experienced a stable connection at 6dB for 50days+ without any resets but during early June the power adapter on my router intermittently failed (sparking sounds) which caused my router to power-cycle thus, I guess, forcing the exchange kit to increase my SNR up to the current level of 9bB. Having now fixed the fault with my router I have currently been constantly synced for 13.5 days but the target SNR has not reverted back to 6dB. As my line length is getting on for 6km from the exchange I am lucky to get 2.4meg downstream at 6dB but now that I am forced to 9dB then the speed has reduced to 2meg. The difference may appear a small one to most but in my case this has a significant negative effect on my ability to use TV on demand, etc.
The stats are shown below. The connection is really stable at both 6 and 9db. I would just like to see the 6bB target reinstated please. It's also worth noting that due to the high attenuation, interleaving has always been forced on by the exchange and this certainly improved things but for some reason the systems have recently switched interleaving off so I am now on fast path and I guess this also demonstrates that I experiencing a reasonable stable connection time.
Is there any particular algorithm used by the exchange kit to automatically reinstate things like the target SNR or interleving status on a connection?

I am moving from the UK to USA. Can I take my iTunes with me?

I have an IPhone and iPad and have my music, videos etc saved on my PC and iCloud. I am moving from London to Chicago so can I transfer my iTunes account to the US when I set up a new PC there?

radioactivem,
Welcome to the Apple Discussions!
Unlike some Mac models, the eMac power supply is not auto-switching. Refer to <a href="http://www.currentsolutions.com/knowledge/countryspeco-z.htm" target=_blank.Volyage Specifications by Country</a>, your UK eMac runs 240v/50Hz while Us power is 120v/60Hz. While the results of plugging your UK eMac into a US power outlet won't be as spectacular as the other way around, it still won't be good for your Mac. The least intrusive fix is to visit an electronics shop and look for a power supply transformer to convert the US power feed to the UK voltage/frequency for your eMac.

I moved from an old macbook to a new one. I have installed Office for Mac 2011. I copied all my files from my old notebook onto a hard drive. On trying to setup my mail, i went into my hard drive and accessed microsoft user identities, office 2011 and it shows the database but wont let me select it. Its almost as if the file is there but not accessable. I desperately need to access my old mail. How do I do this? I am fairly confident that I copied all files off my old notebook. Is there a way for me to search for the Database file? Maybe I copied it to a different location? Urgent help please.

Hello mafrerichs and welcome to Apple Support Communities,
Simplest way is to use Target Disk mode:
How to use and troubleshoot FireWire target disk mode - Apple Support
and hook to another Mac and use CCC or SuperDuper and clone your HD to another drive.
You could also pull the drive out of your MBP and use an external USB case or SATA - USB dongle to hook it to another Mac.

That's a little confusing?

How do I get a modorator to reset my target SNR

At approx 11.30 on 3.5.11 my line continuously dropped and re-established connection for about 20-30 mins (each time synchronising at circa 4800kbps and SNR of 6.0).
By 5.5.11, the (target) SNR had risen to 9db and the line was synching between 3700 and 4200kbps.
On Saturday 7.5.11 I spoke to customer support who reset target snr margin to 6 and line synched at >4800kbps. Unfortunately, in the evening, target snr margin was at 12db with synch between 2800-3500kbps. It has been like this ever since.
I have asked for target snr to be reset to 6db almost every day since then with assurances that it will happen. It hasn't (even when put through to UK help team last night). My line has operated perfectly well for the past 3 years at target snr of 6db. I know both from previous dealings with BT and from these community support forums that BT Wholesale can manually change target SNR to the default of 6th either by a team leader talking to them or a forum moderator instigating the change.
Unless this change is made, I will not achieve the synch speed I know is possible. How do I get a modorator to reset my target SNR back to 6db?

welcome to the forum
have you found the cause of all your reset problems which resulted in your increase in noise margin and reduction in speed? If you get the noise margin dropped to normal 6 and the noise problem is still there then in a few days maybe even sooner you will be back with a noise problem of 12 again
has you connection been stable with noise margin of 12 or has it still been resetting.
you can email the mods by completing the form http://bt.custhelp.com/app/contact_email/c/4951
may take a few days for the mods to get back to you.
it would help your case if you psot you adsl stats showiing your stable connection

Best practice for moving from a G5 to a new Mac with SL

I am receiving my new iMac today (27") and am very excited
However I want to move over using the best practices to assure that I remain excited and not frustrated
My initial thoughts are to boot it up and doe the initial set up - to move my iPhoto library over and to use migration assistance to move the rest of my data files
Then to install all of the extra software that I can find the packages for from the original installation disks
And then finally to use migration assistant again to move over any software that I can not find original disks for (I've moved from Mac to Mac to Mac over and over and some of the software goes back to OS 9 (and won't run anymore I guess)
Is this a good way
OR
will I mess up doing it this way
OR
am I spending far too much time worrying about moving old problems over and would be better off to just turn MA loose and let it do its thing form the beginning?
BTW - mail crashes a lot on my existing system - pretty much everything else seems ok - except iPhoto is slow - hoping that the new Intel dual core will help that

Migration Assistant is not a general file moving tool. MA will migrate your Applications and Home folders transferring only your third-party applications. MA will transfer any application support folders required by your applications, your preferences, and network setup. You do not have a choice of what will be migrated other than the above. MA cannot determine whether anything transferred is compatible with Snow Leopard. I recommend you look at the following:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior 4.1, TechTool Pro 4.6.1, SuperDuper 2.5, and Drive Genius 2.0.2 work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking
will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Target Disk Mode.
5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
1. Set up a local home network: Creating a small Ethernet Network.
2. If you have a MacBook Air or Late 2008 MacBook see the following:
MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- Migration Tips and Tricks;

MacBook Air- Migration Tips and Tricks;
MacBook Air- Remote Disc, Migration, or Remote Install Mac OS X and wireless 802.11n networks.
Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/ (copy the whole folder)

Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
Credit goes to Macjack for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
Written by Kappy with additional contributions from a brody.
Revised 1/6/2009
In general you are better off reinstalling any third-party software that is PPC-only. Otherwise update your software so it's compatible with Snow Leopard.
Do not transfer any OS 9 software because it's unsupported. You can transfer documents you want to keep.
Buy an external hard drive to use for backup.

Target SNR reset request

After the BT outage a couple of weeks ago I noticed a significant drop in the speed of my broadband connection. It was a little unstable for a few days. The line has now stabilised but my noise margin is now at 12db. I am quite a distance from the exchange but can usually sync at 3.5mb.
At the same time as the BT outage there were also some engineers working on a nearby pumping station which has been the source of REIN for us in the past. I am not sure what caused the instability.
Can I request a target SNR reset? I saw some other threads stating to contact the mods from a link in their profile but I cannot see it (only a PM button). Current stats from the router below.
Thanks.
Mark.

Target SNR reset

I have had some REIN problems on my line due to a neighbours treadmill. All sorted now and have had a stable connection for over 3 days. Just wondered if/how I can contact the Mods to get a target SNR reset on my line? Stats from router below (doesn't report up-time). Also a graph from Routerstats showing my very steady noise margin.
Thanks,
Mark.

Recovery of speed/target SNR margin after resoluti...

I have had a line fault on my phone line (noise due to a damaged pair near the exchange) for the last couple of months until I finally got around to getting this fixed. This had resulted in many many frequent disconnections of the ADSL rounter and as a result the target SNR margin for the service currently seems to be somewhere around 12. Since the line has been fixed (perfectly clear phone line now) I was hoping that either a) BT could manually reset the target SNR margin or b) failing that the recovery would not take too long. I raised a fault and was informed that "something has been done" but there was no evidence of this. Having been away on business for the last week I thought I would see what happened over this time but it seems that after a week of no disconnections on the router the synchronisation speed still has not improved. Here is the current status of the ADSL connection

For your connection, the acceptable range of speedsis 2000-7150 Kbps.

Up until the line fault I was synchronising at around 10Mb and achieving 8-9.5Mb download speeds. Has anyone got any suggestions on
a) Whether BT can/will reset the settings for my connection (target SNR margin etc)
b) Failing this how long would it expect to take for the algorithms to automatically recover from this type of event c) Would there be another issue causing this

21CN adsl2+ connections can suffer profoundly from banded profiling.
If the line has seen frequent problems, as is the case, it may take from 3-5 days to see an improvement.
The dynamic line management of 21CN pays a lot of credence to connection history, and coming out of banded profiles can often be lengthy. Your connection even though now fixed has to recover, unfortunately your throughput for the BRAS profile, something totally different ... is not good.
You can either wait and look for improvement over the next few days .... or drop an email in to the moderators.
They can get the banded profiling lifted ... and see how you go.
I'm a little surprised it wasn't requested after the line repair, sometimes it is .... sometimes not.
The noise margin at 12db is not too bad, but should get better with time, if BTw don't reset it.

Moving from 10.4 G4 iMac to 10.6 MacBook

I have a MacBook with a new install of 10.6 and I have an older G4 iMac running 10.4
I want to have the same accounts / files / apps on the MacBook that I have on the iMac. While in the setup of the MacBook, it instructs to use Migration Assistant on the source mac, which I have available over Ethernet. The two systems will not connect. I see that Migration Assistant on the iMac is version 1 while it is version 3 on the MacBook. I attempted to install the Migration Assistant DVD and CD sharing package on the older iMac, but it does not seem to affect the version of Migration Assistant.
So - Is it that v3 of Migration Assistant simply will not run on a G4 iMac running 10.4?
And - without both versions the same we will never connect up?
Would firewire connection be better in this case?
Or - would it be better to transfer from a cloned hard disk that is attached directly to the MacBook?
Thanks!

If both computers have Firewire, then connect an appropriate Firewire cable between them. Boot the iMac into Target Disk Mode. Boot the MB normally. After startup you should find a drive icon for the iMac on the MB's Desktop. Now open Migration Assistant on the MB (not on the iMac.) You should find an option to migrate from another drive or computer that is connected. Note that if you have already created a new user account on the MB with the same username on your iMac account, then MA will refuse to transfer the old account unless you rename it. If you don't want to do that, then you need to create another admin account on the MB that is assigned a different username. Log into that account and delete the account you originally used. After migration you can log into your old account and delete the account you had on the MB before migration. Also, see the following:
A Basic Guide for Migrating to Intel-Macs
The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications Screensavers written for the PowerPC System Preference add-ons All Unsanity Haxies Browser and other plug-ins Contextual Menu Items Applications which specifically require the PowerPC G5 Kernel extensions Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Target Disk Mode.
5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
1. Set up a local home network: Creating a small Ethernet Network.
2. If you have a MacBook Air or Late 2008 MacBook see the following: >MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- Migration Tips and Tricks:

Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)

If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

Big upgrade - moving from 10.4.11 to 10.6.4 AND fro, iPhone 1 to iPhone 4

I realize I have a unique situation and have been unable to find an answer..
I'm making a big upgrade in my system - my questions:
1) What is my best bet for moving my Address Book - currently on PowerBook G4 running 10.4.11 and on iPhone 1 - to my new set up - iMac running 10.6.4 and iPhone 4?
I would prefer not to launch Rosetta - I've avoided it thus far and am hoping to NOT launch Power PC apps on this new machine.. and so I'm not sure if I should sync the original iPhone in order to move the info or if I should migrate it from the PowerBook to the iMac..?
Thanks very much guys and gals - hope you all have a nice day.

Your situation is anything but unique. The easiest method is to use Migration Assistant on your new computer to transfer what should be transferred from your old computer. Both computers support Firewire. You will need a 6-pin to 9-pin Firewire cable that you should be able to find at any local store selling computers - Best Buy, Wal-Mart, Apple Store, etc. Read the following:
