WRT150N Problem with Macs - Slow Speed

Recently replaced my trusty old BEFW11S4 router with a new WRT150N - so as to have N wireless network speed for my AppleTV. But network speed is slow - way slower than it should be, easily 1/10 the speed of the BEFW11S4. The only wireless component was the AppleTV which saw the WRT150N and connected to my network, but transfer speed was dismal. My other Macs are wired connections straight to the WRT150N but they are slow now also - I had to swap back the BEFW11S4 just to get back to speed. I have TimeWarner cable modem, connected right to the router, nothing fancy here. Any suggestions? or does this thing just not like Macs?

Hi… I don’t think, you are missing something in the settings. I think you should reset and reconfigure the router. Reduce the MTU to 1356. Check the firmware. Try upgrade or re-flash the firmware.

Problem with safari slow speed

Hi ,
I realized this problem when it was my first try to use macbookpro retina . it's just a few days that I bought my macbookpro retina. it's too slow compared with my older macbookpro!!!
what should I do?
thnx

Take it into your local Apple Store and see if they can reproduce the problem. You're still within your 14-day "grace" period, so you could always exchange your MBP-R for a new one, or return it for a refund.
It shouldn't be running anything slowly. Unless it's something with your wifi connection when you use Safari. The Apple Store has their own widi set up and can test Safari as well.
Good luck,
Clinton

I am having a problem with very slow start up after expanding RAM on my 2009 Mac Pro.

I am having a problem with very slow start up after expanding RAM on my 2009 Mac Pro (8 Core 2.93GHz). When I run the Mac Pro with 2 x 2Gb RAM it takes 4 seconds before the gray screen, chime and spinning wheel appear.However when I expand the RAM to 20GB the grey screen and chimes appear after a long 20+ second black screen.
The RAM modules are paored 2 x 4GB Crucial CT51272BA1339.M18FMR and 6 x 2GB SAMSUNG M391B5673FH0-CH9, all DDR3 ECC.
Reading articles on the internet, I thought it may be damaged RAM modules, but I have completed memtest and all are okay. I have tried changing the pairs around and if I use any paired 2 modules the Mac Pro starts normally, only when I try running more than 2 modules the delayed start up happens. (black screen 20 Seconds)
I also have tried PRAM and SMU resets after changing the RAM setups, and the issues always occurs when I have more than 2 modules. As you can see I have 6 SAMSUNG modules and even with identical modules the issue happens, when increasing the RAM to more than 2 modules.
The Mac Pro runs fine after the start up screen and can see all the modules, but has anyone else come across this issue, or have any ideas as to why my Mac Pro is taking 20 seconds to start up with 20 GB RAM?

Hi there. Thanks for your comments.
I have tried all the different combinations of RAM setup, and as stated in my initial topic, the Mac Pro boot up time only slows when I have more that 2 modules. Where I place these does not seem to make a difference.
I have taken the Mac Pro to an Apple Reseller technician yesterday and they where not able to find any RAM errors. Apparently the boot up time is within Apple's acceptable parameters for this set up.
Could anyone that is running a Mac Pro 2009 with more that 4 modules of RAM, please let me know if the boot up time is normal. ( the time it takes from pressing the power button to seeing the gray screen around 16 - 20 seconds)
Or is anyone else having the same issues?
thanks for your responce

AD account Login problem with MAC 10.6.8

Hi All,
We have around 50 odd MAC that are connected to windows server 2008 R2. the user were logining in to these MACs using their AD account. Recently few of the random MAC did not allow the user to login using their AD account.When analyzed though the MAC shows that it has connected to the Domain and the server is active with green button it has unbind itself from the server.I had to login in as local user bind the MAC back to get this resolved.
Now the same has started happeneing for most of the MAC that we have and every morning I have login as local Admin and unbind / bind the MAC with the server. this gets reset once the user reboots or shutsdown.
Have tried with few of the below solution but nothing helped:
Solution 1:
<key>mdns_timeout</key>
<integer>2</integer>
The integer value is in seconds; changing it to at least 5 should allow the Mac OS X client to reconnect to the Active Directory domain after a network interruption. In some configurations, a larger timeout value may be required.
You can change this value by using the sudo command and a text editor to edit the preference file directly. Or you can use the Terminal command below, making sure to enter it all on a single line:
sudo /usr/libexec/PlistBuddy -c 'Set :mdns_timeout 5' /System/Library/SystemConfiguration/IPMonitor.bundle/Contents/Info.plist
Solution 2:
I have seen all of the probable solutions and tried everything and still I am getting issues with 10.6.6 and after rebooting the Mac gets unbind. Or the Mac gets Network Accounts Available even when not accessing the list of users from AD. But the thing that I have done that has solved all my issues with AD on the Macs is to uncheck the box to search on all domains. For some reason I am seeing that when the Macs have this option checked, it searches through out the forest on the same domain controller more than once, so AD stops the handshaking of the authentication.
I hope this helps like it did on our Network, since then I have not seen the Macs lose the binding or slow SMB.
If you've tried this please let us know.
TIP: Uncheck Allow Authentication from any domain for Mac AD problems
Wednesday, April 20, 2011
Steven Wells sent a fix and an explanation of problems with Macs losing their binding to Active Diretory:
Unchecking "Allow authentication from any domain in the forest" is working at our college. We have been beating our heads on this for about 2 terms, with no understanding of why it works in some places and not in others. When we found this working, our IT guy said that the Security SID is being duplicated, when it looks in other domain forest, and that is what is causing the problem. This is the first time I have found an explanation for the problem.
If you've tried this approach please let us know.
Solution 3:
Solved it. Create a file in Textedit with the name 'auto_master' (no file extension) with the following contents:
# Automounter master map
+auto_master # Use directory service
/net -hosts -nobrowse,hidefromfinder,nosuid
/home auto_home -nobrowse,hidefromfinder
#/Network/Servers -fstab
/- -static
Place this in /etc/ folder
Hope this helps

TIP: a Kerberos fix for OS X 10.5 and 10.6 binding to Active directory
Friday, November 11, 2011
Mehdi Mafi forwarded a fix he found for problems with Leopard and Snow Leopard binding to Active Directory:
This was taken from Dane Riley's imaging building for DeployStudio.
With Mac OS X Leopard every Mac is now running a KDC (Kerberos Distribution Center). Basically each imaged machine is using the same security certificate and hash. Deploying a single image will deploy the same KDC to every system. This [Apple] article covers how to reset the local KDC so that each system is unique. Basically, do the following:
Launch Keychain Access
Search for com.apple.kerberos.kdc and delete all 3 items
Using Terminal type sudo rm -fr /var/db/krb5kdc
After deployment, perhaps using Apple Remote Desktop to all systems, re- establish the KDC by typing sudo /usr/libexec/configureLocalKDC
If you've tried this approach with Mac OS X 10.5, 10.6, or even Lion, please let us know. .
TIP: More on a kerberos fix for AD binding problems
Monday, November 14, 2011
Mehdi Mafi updated his Friday report about Mac OS X 10.6 problems binding to Active Directory:
You may want to add this. If the Mac keeps unbinding from AD (people can't log in to a Mac), here is how to fix it:
Unbind it from Domain
Launch Keychain Access
Search for com.apple.kerberos.kdc and delete all 3 items
Using Terminal type sudo rm -fr /var/db/krb5kdc
Re-establish the KDC by typing sudo /usr/libexec/configureLocalKDC
Bind it to domain again ( When you bind, uncheck allow authentication from any domain in the forest in: Directory Utilitiy-> Advanced Options\Administrative ) this fix the issue that sometimes it can' find AD under search space.
If you tried this please let us know.
Solution 5:
For Snow Leopard AD login issues, use upper case domain
Solution 6: for .local
To create this StartupItem, create the following directory as root:
/Library/StartupItems/FixADAuth
Then chown it to root:wheel and chmod it to 755. These must also be the owner/permissions on the two files it will contain, below:
Contents of our /Library/StartupItems/FixADAuth/FixADAuth:
#!/bin/bash
. /etc/rc.common
date > /var/log/FixADAuth.log
n=0
AuthSuccess=0
while [ $AuthSuccess != 1 ]
do
id Administrator && AuthSuccess=1 || networksetup -setsearchdomains Ethernet "Empty"; networksetup -setsearchdomains Ethernet middlewich.local; n=$(($n+1))
done
echo Authentication successful: $AuthSuccess >> /var/log/FixADAuth.log echo Operation count: $n >> /var/log/FixADAuth.log
date >> /var/log/FixADAuth.log
Contents of our /Library/StartupItems/FixADAuth/StartupParameters.plist:
Description = "Fixes Active Directory authentication issue";
Uses = ("Disks");
Obviously you'll need to change "middlewich.local" to your own domain name (and the network interface name if your connection is wireless). The script checks to see if it can see the user "Administrator" on the domain, as he's a fairly common bloke, but if you've renamed yours for security reasons then pick another one. I've also included some logging functionality for debug purposes, so you can verify how well the script is working if you need to and time it in your environment before telling the users how long to wait. The /var/log/FixADAuth.log file will contain the date/time the process started, the success variable set to 1 (just to verify), how many DNS operations were required to fix the problem, and the date/time it ended. For us the time difference is normally about +30-40 seconds with around 120-180 operations taking place. Once you're happy with the script, you can strip it down to its bare functionality if you like, like so for us:
#!/bin/bash
. /etc/rc.common
AuthSuccess=0
while [ $AuthSuccess != 1 ]
do
id Administrator && AuthSuccess=1 || networksetup -setsearchdomains Ethernet "Empty"; networksetup -setsearchdomains Ethernet middlewich.local
done
I hope this helps someone!

Problem with Mac Office Password Protection

I'm running Mac OS X 10.7.5 with MS Word for Mac 12.3.5 and MS Excel for Mac 12.3.5.
I created a Word (.docx) and an Excel (.xlsx) document on my Mac at home, both with password protection. I uploaded the documents onto Google Drive. I was able to open the documents a few times with the password on my Mac at home, and on my PC at work. However, now upon opening the docs, Word and Excel say the password is incorrect (both home MAC and work PC).
I know I'm entering the correct password. I'm 100% positive. I was able to open the docs a few times previously just a day before. Now they're completely inaccessible. My questions are:
(1) Is this a common problem with Mac for Word/Excel docs?
(2) Are there ways to recover the password (a dictionary based brute force solution is unlikely to work, as I use non-word passwords with numbers)?
(3) If this is a common problem, are there other alternatives to password protecting or encrypting Mac for Word and Excel docs that don't cause problems?
Any feedback is greatly appreciated. Thanks.

Could just be thats the way it runs on Rosetta. I called in apple to ask if I could return office '04 because I didn't want to take the chance, they were more than eager to return it for me because of the fact it would be slow/maybe have problems running in Rosetta.
I just got iWorks instead till the universal version of office comes out (which if you buy office '04 you'll have to buy the new universal version as well, or so the rep told me).

Somewhere at either Macworld or here I learned that DVDSP 2, DVDSP 3 and now DVDSP 4 "internally" are major re-writes.
Support for HD among a few other items along with QT 7 which comes with Tiger means sincerely that one set of applications/OS is not going to be stable.
Personally I think of all the issues possible its DVDSP vs QT.
Unless you move to DVDSP v4 the alternative is to wipe the disk and go back to Jaguar (10.2) or perhaps Panther but avoid upgrading QT beyond 6. I advocate wiping the disk because I'n not sure an archive and install to down shift to an earlier version of the OS is possible. If it is I'd still worry about mis-matched files in all sorts of locations.

Your advice did not help me. I also installed 10.7.4 combo but the situation is the same.
my internet connection is ok, mail is ok, but app store after 3 resets does not recognize my ID and it says "connection is not possible". Why? I have the same problem in both my mac mini late 2009 and mac book air 2010? Is it a problem of 10.7.4 update? I have to solve this problem and how can i return to 10.7.3 if my last backup was not with 10.7.3???thank you for your kind collaboration...

Email Problem with Mac

Hi, I am new to FIOS so I hope this is the proper board to post in. I set up 2 subaccounts for verizon.net email and configured them for my Mac Mail program. Everything worked well for about 2 days, and all of a sudden the Mail program keeps asking for my password (even though it was saved in my Mail settings) and says the the incoming mail server is offline. I've Googled this issue and see that others have posted about the same authentication error. Has anyone else here experienced - and solved - this problem? Thanks.

I am having the same problems with Mac eMail. I have two Macs, one that is running Lion and the other is running Snow Leopard. I have spent days on the phone with Apple and Verizon and they are blaming each other and neither have a solution. Have you been able to get a response? It looks like this is something that happens from time to time but never really gets fixed.
Please let me know if there has been a fix since the Mac Mail update in July? With the Union Issues Verizon doesn't have enough people to address the issues both in person ( I had a tech come to the house and he didn't know anything about software ) or on the phone. They keep kicking it back to Apple. I also have a couple iPhones and both are working fine. So this seems to be OS X specific. I've had Macs and iPhones for 3 years or more.
Just makes me think something was done to the mail servers they didn't get correct.

Problems with "Mac Help"

My help files, especially "Mac Help", no longer work properly since upgrading to Tiger. If I open "Mac Help", for example, the help window will pop up, but the links will not work (nothing happens when I click on them) and the search feature in help will not work either (the little gray "clock" just spins next to the help bar and nothing else ever happens). Any suggestions on this one? As I'm a relatively recent Mac convert, the help feature was something that I came to rely on. Thanks!

Hi CP,
This is a common problem with Mac Help. When it happens, try first (quit Help) deleting this folder:
Home/Library/Caches/com.apple.helpui
If Help still doesn't work, try then deleting those files:
Home/Library/Preferences/com.apple.helpviewer.plist
Home/Library/Preferences/com.apple.help.plist
(and this one if you find it):
Home/Library/Preferences/com.apple.helpui.plist
See also this KB article for more info
- Mac OS X 10.2, 10.3: Mac Help Viewer unexpectedly quits
and this excellent X Lab FAQ
- Troubleshooting Help Viewer
It seems (not sure about that), that Help caches get easily corrupted when interrupting searches instead of patiently waiting for its internet accessings etc?
Good luck!

Thawte Personal Email Cert - Problem with Mac Mail

Hi, I have requested a free cert from Thawte and there seems to be a problem with Mac Mail (using 2.0.7).
I am using Entourage to send a signed message from [email protected] to [email protected]
If I check mail for [email protected]
Mac Mail reports "There was a problem reading the digital signature for this message"
If I check the same account with Thunderbird, everything works fine.
Anyone else having or had problems?
-chris

Hi,
Thanks for the responses. I requested another cert and that did not help. Here is the process I used after requesting another cert.
1. Logged into www.thawte.com and requested a new cert.
2. Using Firefox, retrieved the cert.
3. In Firefox, backed up the cert to a pkcs12 file.
4. Opened Keychain and deleted the first cert.
5. Imported the pkcs12 backup file. Imported fine.
6. Open Entourage, under tools, accounts, exchange profile, security, selected the cert Thawte Freemail Member.
7. Checked all 3 options (sign, include cert, clear test signed.
8. Created a test message from Entourage to .mac account address.
9. Checked mail with Mac Mail and signature fails.
10. Check with 1.02 Thunderbird and it comes back with valid digital signature.
Next, I sent a test email to my Exchange account from Entourage and that message verifies fine. It just seems to not work when I check my email with Mac Mail.
Thanks!

Problems with monitor -slowing down MAC

Hello, I have a late 2013 MacBook Pro (OS X 10.9.5) and am trying to connect it to a Hanns.G HL 193 monitor. I already have the apple miniport to connect with the VGA monitor cable. However, when I plug it in, the mac becomes veeeery slow (the arrow won't even move correctly) and the monitor just won't light up. The monitor works fine with PCs. The Macbook seems to recognize it, as I can see it in the "displays" option, but it just wont allow me to make it work. What are the exact steps i need to take to make this monitor work? Could it be a problem with the model?
Thank you

Problem with the wireless speed on windows with bootcamp

I've got a problem with the following:
the wireless card of my mac pro is very slow when i run windows on my mac pro with bootcamp
When i just run OSX everything works fine, but in windows, when I connect to the wireless my wireless speed
drops to 11-18mbs.
First I thought that it was a drivers issue, but after the update of bootcamp drivers 1.4 the problem still exist.
First I had a Topcom wireless router now I've bought a Apple Airport Extreme, but the problem isn't solved yet...
The router isn't 2 meters away from my mac.
And the wireless speed is fine when i connect with my dads windows laptop...
Does anyone has a solution? using a cable isnt a solution for me because in September I will move with my mac pro one floor down.

You might want to ask this in the Boot Camp forums. As your wireless work fine under Mac OS X it sounds to be a software issue as opposed to a hardware one which means as Windows users they'll better be able to help.

Audio Problems with Fast/Slow/Reverse Effect in iMovie HD

I have been having problems with the Fast/Slow/Reverse effect in iMovie HD with my movie clips. Whenever I apply the effect (reversing at the same playback speed, not sped up or slowed down), when it is finished rendering the audio is choppy, yet on time (but still backwards, as wanted). Before applying the effect, the preview of it works flawlessly, it is only when it is applied that the audio gets choppy. Extracting the audio will not help either because the video will still be playing backwards while the audio will be playing normally (since it can't be reversed on its own). I have tried other effects on the same clips that don't effect the audio and they work perfectly. Any suggestions? I'd really appreciate your help! Thanks.

now once i turn on straight i get a garbled screen with tool bar on top.
if i start with installation disk 1, i get to the complete start-up and is operational.
upon opening the 'dock' to open safari for example - comuter freezes for a few minutes with spinning rainbow wheel.
what might be the problem?
did run
- safe start-up - no change
- disk utility - all ok
- hardware test - all ok
- extended hadrware test - did not work
- activity monitor - cpu - user 16%, sstem 4%, indle 87%
- system memory (2 gb) - free 850 mb, wired 172 mb, active 970 mb, inactive 51 mb
- disk usage (185 gb) - 135 gb used - 50 gb free
what else can i do? anone encountered similar?
would truly appreciate our kind assistance
thanks a lot

You did not follow my post.
Insert your OS installer disk and reboot while holding down the c key. Select Utilities>Disk Utilities. Then run Repair Disk on your ard drive.
