MBP retina slow Safari when connected to Buffalo

Hi.
I am new to Mac world. I recenlty purchased MBP retina. As soon as I brought to home I connected to WIFI (broadcasted by Buffalo WZR-HP-G450H) and noticed very slow Safari despite uncompromized internet connection. It is always written Sending request at bottom left corner of the Chrome window (same in Safari).
I checked on Windows machine, ipad and and experienced instantanous page loading. I switched back to old TP-Link and got very fast page loading in Safari and Chrome as well. It is very frustrating because I need Buffalo for transfering HD videos wireleslly to my TV and cant use the old TP-link router.
So, could you tell me what is the problem that MBP retina' is very slow downloading pages on Buffalo but quick on old router? Am I destined to have slow brosing speed on Retina?
Thanks for your help.

This isn't customer support - this is a user-to-user forum. You can contact Apple's customer support by calling the AppleCare phone number: find your country here - http://support.apple.com/kb/HE57.
I don't know anything about Buffalo routers - but it sounds as if the router is the problem, since your 'old' router works well.
Sorry,

Internet speed slows down when connected via airport express

Internet speed slows down when connecting via airport express. When connecting directly via the timecapsulethe internet speed is ok, when connecting via the airport express the speed slows down.What can I do to change that? Any suggestions?

Turn off the AirPort Express completely as a test, and move your computer very close to the location of the Express.
As I said before, the Express can only extend the bandwidth (speed) that it receives from the Time Capsule, so the speed that you see there with the Express powered off will be the fastest speed of which the Express is capable.
The Express will make the signal go further when it extends....but it will not make the signal go faster.
A good location for a device that extends wirelessly is a point that is about half the distance from the Time Capsule and the general area that needs more wireless coverage.
If you locate the AirPort Express too far from the Time Capsule or there are more than a couple of walls in the signal path, the signal will be very slow by the time that it reaches the Express....and the Express simply extends a signal that has already slowed down significantly.
If you already have the Express located about half the distance between the Time Capsule and general area that needs more wireless coverage, how many walls, ceilings or other obstructions are there in the signal path between the Time Capsule, the AirPort Express and the area that needs more coverage?
Often, due to obstructions, it is just not possible to achieve good performance when you try to extend a network wirelessly. The solution is connect the AirPort Express to the Time Capsule using a wired Ethernet connection.
There is virtually no signal loss with this type of connection, so the Express can be located exactly where it is needed and it will produce a much faster wireless signal in this type of setup.

MBP retina slow HTTP

Hi, anyone else having problems with MBPr wifi interface for HHTP traffic?
I'm running mountain lion on a 16GB ram MBPr and the HHTP traffic is unbelievably slow. My internet connection is 16Mbit full duplex and ohter protocols as ICMP, RTP and SIP are OK (Skype works). Also, trying with Chrome, Safari or Firefox did not help me.
According to "Network Utilities", my signal-noise rayio is around 23.
Any ideas?
Thanks,
Tkm

I did a test on a fresh MBP retina.
At the very beginning, it shuts down in 2 seconds.
After I installed the antivirus software, McAfee VirusScan for Mac V9.1, it needs 20-22 seconds to shut down.
It seems that the antivirus software is making the final check when turns off.
I uninstalled the antivirus sofware. The time for shut down still remains similar. I guess there must be some residue profile left.
Then if I want to restore to 2-3 shut down time ,maybe I need to press command +R to reinstall.

MBP Retina 15" freezing when plugging thunderbolt display

When I get to work I connect my (in sleep mode) MBP-Retina to the thunderbolt display and *often* the system symply freezes:
black screen and
completely unresponsive to input (mouse/keyboard).
Unplugging the thunderbolt plug and opening the laptop display does little to help.
The screen remains black and the only solution is to FORCE SHUTDOWN the system.
Note also I have had this problem on two different MacBook Pro Retina laptops and
two thunderbolt 27" display with brand new installs of the OS.
Anybody else having this problem? For a >5k$ setup this is REALLY EMBARASSING...

Hi, I am having the same problem.
I have a Mac Book Pro 15' with retina display.
The Thunderbolt Display has an ethernet cord, two drives (one usb and one firewire), and a logitech unifying wireless adapter connected.
This happens so often that I am now turning off/on my MBP before (un)plugging it into the monitor

Nano formatted for Windows, but slow updating when connected to Mac

my girlfriend has an iPod nano and has it formatted to her PC at her home. however, she brings it over to my Mac to grab some songs i purchase from the Store. when connected to my Mac, the transfer rate is that of USB 1 (it's super slow), even though it is plugged into a USB 2 port. is there anything i can do to the iPod to alleviate this? it takes far too long to load a single album.
appreciate any help or advice. thanks!

Since when is putting music purchased from the Store onto other iPods illegal?
As long as they are YOUR iPods, there is nothing wrong with it.
You're not doing that though... you're putting your music on someone else's iPod... that's piracy.
Since when is putting music purchased from the Store onto other iPods illegal?
Again... YOUR iPods... not someone else's.
Plus, it'd be no different than transferring it to her PC and authorizing that, since you can authorize 5 computers.
Right.. it would be no different since that is also illegal.
You can authorize up to 5 of YOUR OWN machines. It's illegal to authorize someone else's computer to play your purchased tracks.
Anyway, thank you for your input though
You're welcome.

MBP logs out randomly when connected to external monitor.

My early 2011 MBP laptop (OS Yosemite 10.2.2) recently started logging itself out. I narrowed the problem to the external monitor which is connected with a Thunderbolt adapter. I installed Thunderbolt firmware update 1.2, that did not correct the problem. When I disconnect the external monitor, the problem went away. Is there something I can do to be able to use the external monitor again?

I know that both displays will turn blue when it is connected, but it turns blue and comes back after the display is connected. It will become blue during a Keynote presentation, while Front Row is on, and while nothing is happening. It doesn't matter if it has been connected for five minutes or two hours, they both change to blue screens and happen very often and in no particular time interval.

Domained laptop - slow logon when connected to non-domain network

Hi,
I'm looking for ideas on how to solve or workaround this issue, so any help would be appreciated. Please note that this doesn't appear to be the usual type of "slow login" problem - in fact I'm pretty certain the issue is caused by public DNS
servers which return placeholder IP addresses for unknown domains, rather than correctly reporting them as being unknown, which is making XP "hang up" looking for servers which don't really exist. Either way, it's causing a lot of problems for our remote
users.
The scenario is this. When domain-member laptops are not on the domain network, they can take anywhere between 5-30 minutes to login. This issue only occurs when the network they're connected to presents DNS servers which resolve unknown DNS
hosts/domains to "placeholder" sites. Whilst Windows 7 laptops do also seem to suffer from this, login delays on those are at worst a couple of minutes, whereas the Windows XP machines are affected for much longer.
Maybe a bit more info will make it clearer :)
The AD namespace shares the external domain, and there are public DNS records for the external domain, but obviously not for internal hosts (like DCs). So internally, the FQDNs of the domain controllers are "DC1.company.com", "DC2.company.com" etc.
When the laptop is connected to users home network, users can logon quickly (<30 seconds), as long as the DNS server offered by DHCP on that network doesn't return an IP for hosts/domains which don't exist publicly. If they do, login takes 5-30 minutes.
I've confirmed this by doing a lookup of the domain on the affected networks to ascertain which DNS servers return placeholder IPs rather than reporting that name resolution isn't possible. For example, OpenDNS's servers (208.67.222.222, 208.67.220.220)
return placeholders, Google's (8.8.8.8, 8.8.4.4) don't. Using OpenDNS to lookup "dc1.company.com" returns their placeholder IP of 67.215.65.132, using Google's returns "can't find dc1.company.com: Non-existent domain". OpenDNS is being used
as an example, increasingly ISP's seem to be using redirection, we're getting this issue with BT and Virgin Media networks, plus a couple of others.
So, if I manually set DNS on a laptop to use Google's servers, then connect it to one of the affected networks, login is virtually instantaneous. I remove the manually configured DNS servers and allow DHCP to present the ISP's own servers, login is
seriously delayed.
From this I can only assume that the fact that the names are resolving at all is causing the delay. I've removed possibly contributory factors from the equation, such as roaming profiles, redirected folders, mapped drives, group policy etc which the
workstation might be trying to access and causing a delay, as well as checking that fast logon optimization is active.
At the moment we're having to tell users to not connect to the network until after they've logged in, which you'd think wouldn't be that big a deal but you know what users are like :)
I appreciate this issue really seems due to bad practice by ISPs rather than with Windows itself, but we really need a fix we can apply ourselves. Reconfiguring users' home networks really isn't an option, there's too many of them, plus that wouldn't
solve the problem when they're using other networks (hotels etc). I don't think setting "good" DNS servers manually is an option, certainly I can't think of a way that would still work when they're connected to our internal LAN.
I'm thinking there must be some way we can set a timeout or something on the workstations so they don't spend so long trying to communicate with what they think are domain servers, but dispite much searching, I've been unable to find anything that works.
So, any help would be gratefully recieved.
Thanks

Thanks for the reply Martin, unfortunately it didn't help matters, but after pondering for a while (and eventually kicking myself for missing something so obvious) I did come up with a solution.
Basically, just set up public DNS A records for the internal servers and point them to 127.0.0.1 (setting up a wildcard DNS entry for the domain also pointing to 127.0.0.1 would do the same thing).
Sure enough logon now takes about 5 seconds, even on the Windows 7 machines (which were only taking a minute or so anyway).
Loopback is the best place to point these to, Pointing them to a public server didn't work, and pointing them at a non routeable private IP didn't work either.
To help anyone else confirming this is also the cause of their slow logon issue - when all three conditions are met it's time to mess with your public DNS!
The FQDN of the domain is public (company.co.uk) and not local (company.local).
The DNS servers in use on the network (or the ISP's DNS servers to which DNS requests are forwarded) return placeholder IPs for unknown host addresses, rather than a "non-existent domain or host" error. This can be confirmed by pinging (or doing an
nslookup) on the affected machine, for a host for which no public DNS record exists (ie ping wibble.microsoft.com) - if an IP address is returned then the DNS servers in use are resolving unknown hosts/domains to a placeholder IP.
If you allow the machine to login on the external network, then run a
ipconfig /displaydns you'll see entries for attempts to resolve internal servers themselves, plus lookups relating to the AD domain such as
_msdcs.gc._tcp._ldap.internaldomain.co.uk and such - these shouldn't be there off-domain, and I believe they indicate the machine thinks it's on the domain, even though it isn't.
Hope this helps someone else out.

After upgrade to lion my mbp goes to sleep when connected to power adapter

I recently upgraded to lion and noticed that my MBP goes to sleep even when it is connected to power adapter. I've set the pref to never sleep when conneced to PA. How do I make it to stay awake? Why did this change in Lion?

MBP reboot after sleep when connected to thunderbolt screen

I work on a macbook pro retina connected to thunderbolt screen. I've set it up to go to sleep after 5 min and go to the lock the screen for security prupose.
But when the computer is connected to my screen, it very often reboots after going to sleep. Any idea why and how to avoid that?

MBP crashes (turns off) when connected to projector

When i connect my mbp to my sharp projector using the included adapter the computer just turns off unexpectedly after about 8 seconds or so. Any ideas whats causing this?
macbook pro Mac OS X (10.4.6)

I am having a similar problem, when I connect my MacBook Pro to an external projector through the DVI-to-VGA adapter. It will eventually kernel panic and I have to reboot. After rebooting, it will eventually kernel panic again, usually within a few minutes.
This never happened in the same setup with my PowerBook G4.
I hope this is fixed quick, I teach with slides and this makes my new computer unusable.

MBP retina slow booting after repartitioning and cloning OS X

I bought a Macbook Pro retina 15" (512/16GB) few days back. OS : Mountain Lion 10.8.4
I wanted to partition the SSD to have Windows 7 in Boor Camp (120 GB), then a partition with ExFAT (260 GB) for shared data between Mac and Windows and lastly Mac HD (120 GB) with Mountain Lion OS X.
After searching in the net, I got this link :http://forums.macworld.com/index.php?/topic/139815-successful-setup-os-x-lion-bo otcamp-win7-data-partition/page__st__14 and followed the steps as described the steps in pane # 21.
So to state again what I did,
1. Used the disk utility to resize the Macintosh HD to 120 GB.
2. Make another partition of 260 GB in the remaining space. So I now have three partition, the first with Mountain Lion, the second (260 Gb) and the third (120 GB) free.
3. Booting with the recovery option, cloned the Mac HD from first partition to the last partition.
4. The system was booting fine with the newly cloned Mac HD (last partition).
5. Then again booting with the recovery option erased the first partition and formatted with ExFat to make it Bootcamp.
After these steps the system is booting fine with the cloned Mac HD bootable drive but booting is very slow. It takes a minute to show up the apple logo. How can I fix this ?
Should I do a fresh installation of OS X in partition 3 ? Please advise.
Thanks and best regards,

I solved the problem of slow booting.
Selecting the Mac HD from the start up disk option solved the problem. There was only one option : Mac HD , so I thought it is selected by default. But after selecting it manually and restarting, now boot takes only a few secs. Thanks.

Very slow queries when connecting through the listener in Oracle 10.2.0.4

Hi,
I have a 10g database with a little table (2 columns, 9 rows).
When i connect to the db through the listener (sqlplus system/manager@SID) and run this query : select * from table, the execution time is about 500ms
When i connect to the db by setting the ORACLE_SID to SID (export ORACLE_SID=SID; sqlplus system/manager) and run the same query, it's 10x faster ...
The listener is : TNSLSNR for Solaris: Version 10.2.0.4.0 - Production
The database is : Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
Any ideas ?
Thanks ... (i'm a newbie in oracle and in english ... so excuse me in advance)

I'm re-reading some docs on exactly how to "walk the clock" in reading the above. If you are interested, see if you can find a copy of "Optimizing Oracle Performance" by Cary Milsap. It goes into great detail about how to interpret these traces.
The "ela" value is the elapsed time of the wait, in micro-seconds (1 ms = 0.000 001 second). Unless I've slipped a decimal position, you have 0.52081 sec (a whisker more than one-half second) in network wait time, that doesn't exist on the bequeath connection. That is your "about 500 milliseconds".

Slow boot when connected to network

Hi
I have a macbook pro and an imac, both recently updated and have noticed that since the update there is a significant delay, right at the start of the boot process, if either machine is connected to a network. Both my machines are running boot camp with windows 7.
On both machines, if I hold the "ALT" key to select a disk when powering on and the machine is connected to my network (which uses static IP addresses), there is a delay of a minute or so before the boot disks are displayed. If they are not connected then the disks are displayed almost immediately.
My question then: What's going on? The IP addresses are static so what could they possibly be waiting for?
Cheers
Mark

Hi,
How about Safe Mode? Have you tried it? In addition, please try to upgrade your BIOS and motherboard driver to be latest for test.
Be warned: Flashing BIOS is a risky process. If power is interrupted during the update your machine will be rendered unusable.

Slow YouTube when connected to home wireless broadband DSL2+

I'm experiencing really slow YouTube downloads. I'm connected to my home wireless broadband which is really fast (17000/880, however downloading YouTube content on the phone takes ages. Any suggestions ?

The answer is set your Wifi to B only and all the speed problems with the iPhone 3G will be fixed! There seems to be a problem with the 802.11G on the iPhone in my experience.
