Issue with MacBook Pro (mid 2009) wifi multiple AP signal 'confusion'

I'll try to explain this as best I can, not being an expert in networking!
I recently upgraded my router from a Linksys WRT160N to an Airport Extreme, in the hope that it would do a better job of broadcasting a stronger wifi signal throughout my house. Whilst it is improved, it's still no good enough for streaming to my iPad 2 where I want in the house. Reading around on the web I discovered that I should be able to use the Linksys as an AP to extend the effective range of my wifi network, as long as it is hardwired into the base station via Ethernet (no WDS support on the Linksys model).
So, I managed to get this all up and running, disabling the dchp on the Linksys, fixed ip allocation etc and using the same SSID and passwords etc. All is well with the iPhone and iPad2 access - they just automatically switch to the strongest signal no problem when I move around the house. Cool.
The issue lies with the MBP - I have a favoured spot in the house where both the broadcast signal from the AEBS and Linksys are very strong, and the MBP gets all confused. opening up the lid from standby it searches for the wifi (bar moving up and down the signal indicator) and then just has an exclamation mark. I try to manually select the SSID but no dice. I have to switch the MBP adaptor off and on, rescan avail networks, and lo and behold two versions of my SSID are shown. Select one and then it connects. However, I have to go through this whole exercise every time I pull the MBP out of standby, which is very irritating.
I do have a workaround - if I name the SSID on the Linksys something different, the problem goes away. However, i effecktively now have 2 wireless networks & I then have to manually switch between the two SSID's to get the strongest signal depending where I am in the house. It's suffices for now but not ideal.
What I don't get is why is it only the MBP affected & the iPhone & iPad 2 are fine? Is this anything to do with the 2.4 ghz & 5 ghz being broadcast by the AEBS getting all mixed up with just the 2.4 ghz being broadcast from the Linksys??? Both 2.4 & 5 ghz are broadcasting the same SSID.
Any help appreciated.

OK - fixed this now. By setting the 5 Ghz channel on the AEBS to a different SSID and putting this to the top of my priority WIFI connections on the MacBook Pro then it ignores the conflict between the 2.4 Ghz networks being broadcast by the Linksys & AEBS. No more hanging connection when I resume the MBP

Yosemite Issues on Macbook Pro mid 2009

I have a macbook pro with a 2.8 Intel Core 2 Duo and 4 GB of Memory. I have more than enough HD space. Ever since I upgraded to Yosemite, I have been having issues with running my mac. It runs super slow, every program takes 5 minutes to open. If I open iTunes and iPhoto, I might as well walk away and come back later.
This issue only started happening with Yosemite. Is my system to old to handle it? Do I need to upgrade or what can I do. I'm a web designer and user Photoshop and all of the adobe programs a lot. I can't sit and wait 10 minutes to open a program, please help.
Thanks,
Francisco

Hey, I do not have the exact same problem but trying to update to 10.9.2 causes my macbook to be stucked in black screen + curser after boot up. I have looked through forums for an answer but nothing worked for me (such as reboot, reset NVRAM, disk verification, disk/permission repair, password entry, control-option-command+8, fresh osx 10.9.2 install). To be sure that my disk is properly working, I have installed the original snow leopard os, this worked fine. I also could access the recovery console.
To be able to use my mac I have now restored to 10.9.1 from my TM backup. Dont know if I should report this strange behaviour to Apple. Maybe there are others who have discovered the same issue?
Let me know pls.
cheers.

After several repairs, still having heating issue with MacBook Pro (mid '09)

EDIT: this post got removed the first time for not being constructive enough. I've now edited the post.
This is going to be a lengthy post, so bear with me.
2 months ago, I suddenly noticed my MacBook Pro (medio 2009, 15", 4GB RAM, GeForce 9400M) heating up a lot harder than usual. I'm familiar with the heating issues these laptops have, but this wasn't normal. Looking at iStat Pro, I saw my fans almost taking off like an airplane at 5700 rpm, while watching only a livestream on my browser. I know Shockwave Flash takes up quite a chunk of your CPU, but I had never encountered this problem beforehand.
The biggest problem wasn't just the heat or the fans, but the fact that my computer also started reacting rather slowly. Sometimes I'd even get beachballed, or the whole browser stopped responding for half a minute...
So I tried to see if gaming was still an option. Of course not. I had been playing League of Legends for several months without any issues. Whilst playing, I'd kick up my fans manually to about 4000 rpm, and they'd stay there throughout the whole game. Now, when I start up the game, it plays smoothly for the first 2 minutes. After the temperatures rise to a critical level, the fans start spinning up to 5700 rpm, and the whole game plays like a powerpoint presentation.
On a sidenote: it sort of 'lags' every 1-2 seconds, and sometimes, after a long period, the game acts somewhat normal again (20 mins). This game uses wine to run, which isn't the most optimal way. So I tried playing Team Fortress 2, too. Probably even worse results! (but again noticeable 1-2 second interval lags)
Before anyone starts screaming: "Don't use your Mac for gaming!" etc., I wish to point out that these two games had been running perfectly for the past few months/years. Something's definitely wrong.
After looking for some solutions myself, I decided to go to an authorized Apple Service in my city. A few days later, they told me my logic board was broken, and I had to pay almost 700 euros ($ 900-1000) to replace it. So I did. I got it back, but it wasn't fixed. Brought it back in. Got it back a week later: "Your new logic board we got from Apple was already broken, but we hadn't noticed. We put a new one in it. It's fixed." Again, same problem.
We're almost 2 months later and 700 euros poorer, still no result. I've brought it in about 6-7 times now, here's a list of what they've tried so far:
- In total 3 new logic boards
- New MagSafe (because they discovered it was giving too much power too my laptop)
- Fresh re-install
- Replaced RAM
- Checked fans etc. (they do this by default)
- A few tests which proved that it was repaired (but I have my doubts with these tests...)
They told me now that it's fixed, and they basically won't look into it anymore. I must contact Apple myself, if I wasn't satisfied. The tests they performed showed no signs of heating issues. (One of the tests was playing 4 1080p movies at the same time. When I watch a 1080p movie on Youtube, my laptop is taking off like a plane) They ran a stress test all night long, showing no temperatures above 98°C. I got it up to 105°C in a few minutes according to iStat Pro.
They advised me to install Mountain Lion, which would make the issues with "high-performance sites" go away. I haven't seen much improvement, though.
This whole experience has been quite frustrating, especially now that I'm gonna need my laptop for University again. Isn't there anything I can do? I've paid almost 700 euros and missed my laptop for 2 months, without any results.
I've got more information regarding the issues if needed, ask away. I'm getting desperate.
I've been browsing around the support communites, and found that a lot of people are having issues since they upgraded to OS X Lion. Could this be the case? Should I try downgrading to Snow Leopard?
I've also found a few topics on refreshing the cooling pasta on the heatsink. Would they have noticed any problems with this after replacing the Logic Board several times? Or should I check it myself? I'm not too keen on opening up my laptop myself...
Nick.

Thought of buying Parallels? Fusion?
Might want to see if this gets moved to the MacBook Pro forum.
I'd think Windows 8.1 is smart enough (what I use 90% time since the Dev Preview came out couple yrs ago it seems like) to find the driver.

Issues with MacBook Pro mid 2012 and SSD data 3

I installed a Samsung SSD in my macbook pro model A1278, it work very well since yesterday; maverick 10.9.2 run very very slow and it have a lot of lag. And so ai provide to reinstall the native HDD and it run very well. I decided to buy another SSD of OCZ, the previous was Samsung 830, and the system didn't recognise the ssd, but if i link it with usb it work. Anyone have the same problem?

Thank you for your reply :),
I verified multiple times to ensure that the MBP-R and the ATV2 were connected to the same wifi. That's all that would be required with my network set up since there are no configured sub-networks. All of the devices connected can see each-other. I also verified this by checking in the router. Sure enough, the ATV2 is listed with all of the other devices.
There were other problems related to Internet content with the ATV2 when I shipped it in for repairs under warranty. It was constantly disconnecting and reconnecting, and no matter what, it wouldn't remember any settings. I noticed these defects after I asked this question. I suspect that, because there has been some horrible weather and lots of power surges here, that it became damaged from a surge. This was not plugged into a surge protector like everything else, so I brought that on upon myself unfortunately.

Negotiated Link Speed on MacBook Pro mid-2009 with Kingston SSDNow v300

Hi,
I have a mid-2009 MacBook Pro (13") with Kingston SSDNow v300 SSD drive with Mavericks OS X installed.
I've noticed from different forums that many users have the same problem that I have: SSD drive's Negotiated Link Speed is only 1,5 Gbps, although MacBook Pro mid-2009 should support 3 Gbps speed.
My system has EFI 1.7 firmware update (MBP55.00AC.B03) installed in and System Info says that 3 Gbps Link Speed should be possible:
NVidia MCP79 AHCI:
Vendor:    NVidia
Product:    MCP79 AHCI
Link Speed:    3 Gigabit
Negotiated Link Speed:    1.5 Gigabit
Physical Interconnect:    SATA
Description:    AHCI Version 1.20 Supported
Many users have tried to reset NVRAM and SMC and I have also done these steps, but with not any improvement.
Some users have mentioned that MacBook Pro mid-2009 has a poor SATA ACHI chipset (NVidia MCP79) and SATA III SSD drives won't work on SATA II speed unless SSD drive is forced to work on SATA II speed by firmware update or by some tweaking tool. Is there this kind of tool available for Kingston SSDNow v300?
One user says that he got 3 Gbps Negotiated Link Speed on Mountain Lion, but after installing Mavericks, speed dropped to 1,5 Gbps (https://discussions.apple.com/message/23549859#23549859).
So, is there any way to get Negotiated Link Speed to work on 3 Gbps on Kingston SSDNow v300 with MacBook Pro mid-2009 (for example by installing an older version of Mac OS X) or do I have to buy a new SSD drive from another manufacturer to get 3 Gbps Negotiated Link Speed to work on my machine?
If the last option (to buy a new SSD drive) is the only option, would it be wise to look for an older model, a SATA II drive, (maybe OCZ Vertex 2) to get 3 Gbps speed?
Thanks!

Hi
I was just as frustated as you after installing the Kingston v300. I mean it's a solidly built drive with the reliability of kingston (I've been using their RAM for years and years in my desktop PC without problems). Unfortunately, for a the last 3 months I had it in my 2009 unibody white macbook, it was stuck at link speed 1.5.
I've been searching in forums since then without any solution. Even the update for bios is not available for my model.
I just tried the SMC reset after reading the blog.
http://thenextweb.com/lifehacks/2010/12/04/how-when-why-to-reset-the-pram-smc-on -your-mac/#!w3XEY
On reboot, everything seemed faster, so I checked the negotiated link speed and it was at 3 instead of 1.5! Yay! Then I checked the disk transfer speed on Blackmagic Disk speed test and it roughly doubled from 138 to 260MB/s. Now, I'm not going to shutdown or restart...
I hope this post is useful for people like me stuck at 1.5 Gbps speed. Good luck

How to make a MacBook Pro (mid 2009) work properly with a 3M Streaming projector?

Ok, so I have a MacBook Pro (mid 2009), a 3M Streaming projector and very annoying problem.
When I connect my MacBook Pro with a Mini Displayport to HDMI adapter to the 3M projector, I get a pink tint, like a filter over the image, it’s very frustrating.
This are the tests I’ve done:
1. I tried the adaptor and the projector on a different (more recent) Mac -> It worked fine.
2. I tried connecting my MacBook Pro to a different not HDMI but VGA projector -> It worked fine.
3. I used some Terminal code I found on the web to force the Mac to send RGB signal, don’t know if that has anything to do with it, but I tried anyway -> Didn’t work
So I’m confused, it’s not the physical port of my MacBook cause it worked fine with a VGA projector, It’s no the 3M projector and it’s not the Mini Displayport to HDMI adaptor cause it worked fine on a different Mac.
So what is it?
I’m totally desperate, I haven’t been able to solve this problem, so if you guys can help me you will be my heroes.
Thanks.

Yes as Clinton says this is correct.
I've used a Sata to USB connector which is only a few pounds instead of an enclosure for the clone, but then I wasn't keeping mt old HDD. But that's an option if you don't need it.
I also use Carbon copy cloner as this will clone your recovery partition as well. Apples disk utility will also clone drives but I'm not sure that it copy's the recovery partition.
I highly redomend my Samsung 840 pro 256Gb - it's about the fastest drive you'll get (nearly) but is backed by Samsung's unrivaled SSD reliability and 5 year warranty. I've also used an 840 basic model on an older macbook and was equally pleased.
Crucial's drives are reliable mac friendly drives but are somewhat slower on the write speeds vs the 840 Pro.
I'd avoid OCZ drives due to so many failures across their range although they do have great reviews and some models just edge the Pro on speed although it's fairly negligible.
As Clinton says, avoid the Samsung Evo drive. I wanted to buy this drive as it is a great drive - but there are many users that have had compatibility issues with it when installed in a Mac. This may rectified on a future firmware update possibly, but until it's proven I would avoid it for now.

I put a new hard drive, with all of my information from my old drive installed on it, into the computer. but now have the blinking question mark folder. I see that it means that it isn't reading the new hard drive.
did i miss a step between transferring all of my information from my old hard drive to the new hard drive and installing the new hard drive into the computer. I believe that i installed properly. it was quite easy.
thanks for your help

It means there is no bootable system on the drive. If you still have access to the old drive, then I suggest you boot from it then clone it to the new internal drive. Use OPTION boot to boot from the Recovery HD on the old drive:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     1. Select Disk Utility from the main menu then press the Continue
         button.
     2. Select the destination volume from the left side list.
     3. Click on the Restore tab in the DU main window.
     4. Select the destination volume from the left side list and drag it
         to the Destination entry field.
     5. Select the source volume from the left side list and drag it to
         the Source entry field.
     6. Double-check you got it right, then click on the Restore button.
Source means the external old drive. Destination means the new internal drive.

Airdrop gone with Yosemite on MacBook Pro mid 2009

Why was Airdrop removed on a MacBook Pro mid 2009? It worked just fine under Mavericks and before. How do I get it back?

After several restarts of the older Mac, they now see each other in the Airdrop window. I forgot to write that I already set the Airdrop window on the newer Mac to show older Macs before. The restarts helped in a way. I don't know what was wrong.

Can't enable Handoff in my macbook pro mid 2009

hey buddies
I finally upgraded to OS X Yosemite with my macbook pro mid 2009 but.. i kind of upgrade because the handoff and continuity options paired to my iphone 5
I see in many reviews and blogs that I need to open System preferences > General > Allow handoff.. but THERE'S NO ALLOW HANDOFF option....
here in the picture below you can see that there's no option for that..
what should I do? is there any issue with that?

There is a tool available, unsupported by apple that enables this feature on older Macs. I have not tried it yet as I don't have iOS 8.1 installed, but people are claiming it works to enable on unsupported systems. As usual, use at your own risk. https://github.com/dokterdok/Continuity-Activation-Tool/

MacBook Pro mid 2009 HDD to a Kingston SSD SATA drive - Problems

Hi
I own a MacBook Pro Mid 2009 and I'm running OSX Mavericks with Windows 8.1 Pro Bootcamp. I wanted to upgrade to an SSD drive and after reading the great reviews on Amazon, I purchased a Kingston 240GB SSD 2.5" V300 SATA 3.
Many of the buyers had installed the SSD drive on Macbook Pro, including "mid 2009' models without any real problems but I've just spent the best part of 3 hours trying to install the drive but so far, it has not worked and the problem seems to be that, although the Acronis True Image software that comes with the drive to 'clone' the source drive and install it onto the destination drive (new SSD drive), I get a message which states, "WARNING: After migration, the O/S will not be able to boot from the destination disk in the BIOS - If you want to boot from the destination disk after migration, you need to enable UEFI booting in your system and then restart".
During one of my first attempts to install the SSD drive, I removed the original HDD from the MBP and installed it in the supplied 2.5" caddy and and connected it to the MBP via the USB cable supplied then installed the new Kingston SSD SATA3 drive in the MBP, powered up and then rebooted. The Acronis bootable software launched and after choosing 'clone disk', cose source and destination drives, I got a message saying: "The selected disk will be migrated as is (disks layout will remain GPT)". "After operation completion, operating systems will not boot from the destination disk in the BIOS".
My system has the latest available Boot ROM Version (MBP.00AC.B03 and the SMC Version is 1.47f2 and as far as I am aware, Apple computers have no BIOS that you can access like on Windows computers and instead use EFI instead.
Both drives had Extended Journaled GUID Partitions on them and what baffles me is that other buyers of these Kingston SSD SATA3 drives appear to have managed to install the SSD drive, but I've had to give up.
I would really like to get the SSD drive working but so far I've failed. Any advice would be appreciated and I'll try it out before reluctantly returning the drive for refund.

Hi
Thanks for your reply.
Yes the Acronis software is Windows but I read through a lot of reviews on the Kingston SSD SATA 3 drives Amazon and from what I can gather, after removing the original drives and installing that in the 2.5" caddy and then installing the new SD drive in the Macbook, those buyers then used the software to boot from and clone the source drive to the new drive.
I'm not sure if I mentioned it in my first post, but I did use the Disk Utility in Mac OSX and erased, formatted and partitioned the drive and then pushed CMD + R at start up but I was not able to install a copy of the OS because the drive was not recognised.
I think I also used the disk utility in Windows and then tried again in OSX but no luck. I'm no expert but as stated above, the issue seems to be that the SSD drive is not booable in the BIOS (or Mac equivalent).
The SSD drive is SATA 3 and I'm sure that the SATA ports are SATA 1 on my MBP and maybe that the problem Perhaps someone can confirm this.

I updated to OS X Mavericks and now trying to run Logic Pro X on a MacBook Pro mid-2009, using an M-Audio Axiom 49 and an M-Audio Fast Track Pro... Logic keeps telling me that Mac OS X MIDI Services are not available... How do I solve this problem?

I updated to OS X Mavericks and now trying to run Logic Pro X on a MacBook Pro mid-2009, using an M-Audio Axiom 49 and an M-Audio Fast Track Pro... Logic keeps telling me that Mac OS X MIDI Services are not available... How do I solve this problem?

I just checked to see if the update to OS X Yosemite 10.10.1 solved any of the issues outlined in my previous post, and to my dismay, nothing has changed -- all of the previous problems persist.
My iMac (8) -- it's renamed itself eight times since the recent troubleshoot with the Apple tech rep -- shows up as a shared device in Finder on my MacBook Pro, but when I click on it, I cannot establish a connection using "Connect As". So I've attempted to connect using the menu "Go/Connect to Server...", using both (alternately) the iMac's name and IP address, to no avail. I get a message which reads: "There was a problem connecting to the server 'Peter's iMac (8)'. This server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
Here's what I know:
The server -- Peter's iMac (8) does exist;
The server -- Peter's iMac (8) is available at this time;
The server name -- Peter's iMac (8) -- is correct, as specified in the system sharing preferences;
The server IP address is correct, as specified in the system sharing preferences;
The network connection is active when I attempt to connect.
I'm convinced the problems stem directly from the OS X Yosemite update. None of this was ever remotely an issue in the previous OS X's -- any of them. This is maddening! What can be done? Apple?? Anyone???
