Prohibitory sign at startup / Brand new MacBook Pro 2011

Hi guys,
maybe you can give a little more info about this.
I purchased my MacBook Pro 15.4” QC i7 2.0GHz last Tuesday and right away I put an Intel SSD in. A few days later I got a 'prohibitory sign' error. I have read the support article for this.
My SSD is INTEL X25-M SATA2 SSD 160GB 2.5" RETAIL (SSDSA2MH160G2R5). After when I first got the sign I formatted my SSD (Zero out data) and installed Show Leopard from the DVD. All seemed fine, even the boot time shrank from 40-50 sec to 15. And a day later I got the 'prohibitory sign' again. So now I'm confused... The SSD is compatible with Mac. The only thing I discovered today is that a new firmware is available for the SSD. Maybe this will solve the issue?! Note that this sign appears randomly. After when I got the sign I forced shut down and after turning it on again the startup went as it should... So most of the time everything works fine, but sometimes I get the sign.
Have any of you experienced something like this using Intel SSDs?
Thank you.

i have had my macbook stolen before
the apple store people will say you cannot do anything
you have to call tech support, its the tech support people that will flag your serial number on your laptop
unfortunately with you laptop only being a few minutes new, and they probably stole the whole thing with box and components you have a lower chance of ever retrieving it,
i feel for you man, i know what it is like to get your mac stolen

Brand new MacBook Pro 2011 got stolen

sorry I can't find a place post this so I post this here. This unfortunate event happened yesterday. I got my brand new MacBook Pro 2011 from the apple store and I went to pick up takeout at a plaza 10 mins away. My car got broken in and my Brand new MacBook Pro was stolen. I just went to pick up take out for 10 mins only. I m wondering if there is anything that Apple can do such as tracking the serial number? I have the receipt with me luckily.
Thanks

Brand new Macbook pro 2011 15" screen shifts

Hello there
I've had my new macbook pro for 4 days and I've been having problems with the screen.
Time to time the screen would begin to flicker a little for a minute, and finally shift completely to the left. The left part that gets cut off the edge reappears on the right end of the sceen. There is a black bar about an inch thick where the split occurs. The cursor still works at this point, but is useless and I have to restart my laptop.
This shifting has happened 6 times so far I think.
If it doesn't shift, then the screen would turn completely black but it's not turned off (the music that is playing keeps going but is 'stuck')
This blackout has occured 4 times.
The problems are occurring more frequently now.
*lol I was in the middle of typing this on my macbook when it shifted again (this time halfway) and now I'm on another computer and I recovered everything I typed. Thanks apple.
At first I thought it was because of Photoshop cs5 or youtube, both of which were running when the problems occurred. But now the problem occured again without any of those programs running except for Google chrome.
I would appreciated some advice. Thank you
15.4 inch 2.0 GHz, with base configuration

You have 14 days from the date of purchase to exchange for another with no questions asked.

OS X Lion Crashing on my brand new Macbook Pro 2011 (721)

I have bought a 2011 Macbook Pro (721) 2 weeks ago and then the same day i upgraded it to OS X Lion. (10.7.1)
my os x lion have crashed so bad several times during this 2 weeks that i bought my mac, in a way that i could do nothing but holding the power button, and i supposed that apple's operating systems are not that easy to crash.
is it normal? I'd say it happened about 5 times in 2 weeks and it started from the second day. is something wrong with lion updates? i have read some forums that they say something may be wrong with firewire update.
** by the way in this 2 weeks i have not done anything special or any hard proccessing job. i just used it for internet.

Startup disk almost full for brand new Macbook Pro with Mavericks

I recently purchased a brand new Macbook Pro Retina that runs on Mavericks. I keep getting a message saying that my start up disk is almost full, even though I have almost no files on the hard drive other than whatever was pre-installed by Apple. Does anyone know how to resolve this problem?

ITunes downloads fast on old Mac mini but slow on brand new Macbook Pro on the same WiFi network?

Hi all,
I have an old Mac mini that's from around 2008 and runs on Snow Leopard. I also have a brand new Macbook Pro with retina display that's running Mountain Lion. Both running iTunes 10.6.3.
I never noticed anything wrong with my MBP's connection speed until last night when I downloaded a free TV episode from iTunes. The download speed varied between 20KB/s and 40KB/s and it took me 7 to 8 hours to download a single episode. I checked my internet connection but there was nothing wrong with it, SpeedTest.net told me I had a download speed of 94MB/s and upload speed of 80MB/s, it was only iTunes that was unbearably slow.
Today I was browsing iTunes again and was planning to buy some movies, but again it took forever for the trailers to download. So I fired up my Mac mini just to see if it would be just as slow. Turned out my Mac mini could download the same trailers from iTunes at a much higher speed than my MBP (around 3MB/s on the ones I tested).
So what gives? They are on the same Wifi network provided by an Airport Extreme, and although my iPhone and iPad are also connected to it, no one else is doing any heavy duty downloading.
Thanks in advance!

Why wont my brand new macbook pro boot to an external disk?

why wont my brand new macbook pro boot to an external disk? I have the 10.7.4 on both. The MBP came with it so I installed it onto the hard drive i have been using the same way with an older macbook pro but the new MBP does not see the startup disk. So i installed the same version of the os onto the MBP by hooking it up to my imac as a target disk because it would not recognize the install usb stick. Now the brand new MBP doesnt start up

I had the same issue. The 2012 macbook pro has a different 10.7.4 build that is not yet available for public release. It won't boot no matter how much you try. You need to wait for Mountain Lion and create a start up disk from ML. Apple most likely will release a 10.7.4 update for the 2012 models, but they are focused on ML now.

Brand New Macbook Pro (2013) Running Slowly?

Hi,
I just bought a brand new macbook pro with retina display about 4 weeks ago (2.5 GHz Intel Core i5 processor, 8 GB 1600 MHz DDR3). My internet seems to run slowly on it. For example, it takes longer for streaming vidoes to load compared to my old 2008 basic model macbook, when connected to the same network. Also sometime email and other websites take unusually long to load (again compared to my old macbook, same network). I only have safari open with all other applications closed. Suggestions?

try changing your dns server. network - advanced - dns - then click the plus sign and add the numbers you see on the image below.
see if that helps your internet connection.

Strange wifi problem on a brand-new MacBook Pro

Hey there, I'm new here. Desperation has got the better of me, and I hope I can get some advice.
So, last sunday I bought a brand new 13" MacBookPro with 2.8g i7 processor and 10.7.2 OS (I can't update to 10.7.4 because System Update tells me the download has been tampered with or corrupted after I waited 2 hours for it to finish, but I'm trying a direct download from the website). Here's the exact product: http://www.amazon.com/Apple-MacBook-MD314LL-13-3-Inch-VERSION/dp/B005CWIZ4O/ref= sr_1_5?ie=UTF8&qid=1340301247&sr=8-5&keywords=macbook+pro+13
Everything is all perfect except for a strange wifi problem. Note that the wifi does not turn-on or off, it doesn't disconnect after 'sleep', it doesn't get less speed, it doesn't constantly leave a preferred connection (once I chose my home wifi it always connects to it no problem). The wifi bar is always full. What is wrong is that the internet is kinda 'glitchy'. The best metaphor I can think of is that it's like a car that has to be pushed down the road before the engine can start. Please, bear with me because this is kinda hard to explain and I'm not good at tech lingos.
One of the symptoms is browsing can get really slow and inconsistent, almost as if the wifi gets turned off in the middle of browsing. For example: if I look something up on Google and then open 5 new tabs, probably only 2 or 3 of those tabs will eventually load while the other two will not get past the long 'http:.......google.....etc etc' address and will eventually show one of those 'error loading page because there's no Internet connection' notice. This happens a lot. Sometimes I have to refresh/retry loading a page a couple of times before it finally loads, then usually everything will get back to normal and I will be able to open multiple tabs with no problem, but in a couple of minutes I would try to open another site and the problem will start again.
So I tried to see how it does with downloading using iGetter. Fortunately I also have a Macbook (white-plastic casing one) and my brother has an old 2006 MacbookPro so I can compare. With those two older Apples iGetter starts receiving data in less than 8 seconds after I click Start, while my brand-new Macbook Pro can take up to 15-20 seconds, sometimes it doesn't even start at all and I have to re-click the start button. But once the download actually starts (on my new MacBook Pro), it downloads like normal, it doesn't stop and the speed is also as good as I can get. Strange huh? Hence, like a car that has to be pushed before the engine starts.
I also tried 'speed testing' from a website with all 3 laptops. On my old MacBook and my brother's MacBook pro, once I click 'begin test' it takes only a couple of seconds of 'ping' before the download/upload speed measurements start, but with my new MacBook Pro (just like with iGetter) it takes up to almost a minute before the measurements start, sometimes it won't start at all and I have to re-start the test.
Well, thanks for reading. And hope you can help me shed some light into this. Because it is really preventing me from really enjoying my new MacBook Pro. And if this is most likely a hardware problem, I'd better get back to the store and try to get it replace or something while it's only been 5 days. *cheers*

Hey guys.. Thanks for the replies. Unfortunately, I bought the MacBook in Indonesia where there are no such thing as an AppleCare. The only option is to leave the Apple product to one of the 'Authorized Apple care centre' and have whoever do whatever to it without guarantee of success. As for returning it and getting a brand new one, I also don't know if there is such a deal here, but that's actually a good idea, will try to go to the store tomorrow. Although, I'm worried that the problem might be with OSX Lion or something and getting a new one won't help.
mark75090, I've tried resetting the router when I first noticed te problem, didn't work though. I've checked my new MacBook's wi-fi (option+click wifi bar) and it says 'PHY Mode: 802.11g', so does my MacBook and the old MacBook Pro. I don't know what those mean though, and I don't know whether or not my router is an N., can you tell me more please.. I have tried with the other two turned off, and only the new MacBook using the wi-fi but the problem persists. I have also tried connecting directly to the router, but as I described, the problem is too subtle for me to notice the difference.
Also, if I create a brand new Wi-Fi connection in network preferences and connect to my router through the new Wi-Fi profile, the problem seems to be gone for an hour or so, then it always comes back though. I have also just finally installed 10.7.4, but it doesn't help either.

I have a white vertical line down the right side of my internal brand new macbook pro 13" display

I have a white vertical line down the right side of my internal brand new macbook pro 13" display. I've done the following:
-Shutdown the computer, and restarted in Safe Mode by pressing the Shift key after the restart tone
-Shutdown the computer, and restarted by pressing Command, Option, P & R after the restart tone
-Checked display resolution, Best for Retina
-Hooked it up to a Dell external monitor and via projection to screen. There are no lines on the external or secondary screens
-Just curious, I ran a color utility which can not repair 4 items, maybe this is another issue.
This is a brand new Macbook Pro, just out of the box. It was fine for two days without any issues, fine last night while in use, opened it up this morning with the line.
Anyone now how I can fix this on my own?

If you are within the first 14 days from the date of purchase, return the MBP for a refund or an exchange. If you are after the first 14 days of the date of purchase, have the MBP repaired under the warranty provisions.
Ciao.

I bought a brand new MacBook Pro Mid 2014, and my battery cycle count is on 2!!

As I said on the question, a brand new MacBook Pro I bought recently which I haven't even put on charge yet already has a cycle count of 2!
I'm just curious if this is normal and I want to make sure that I received a brand "new" one not a refurbished one.
Did anyone else order a new laptop and have cycle charge of 2 or more and is this normal or not?

The factory charges the battery, one cycle, they may then test that particular MacBook Pro as part of the production testing and it ends up with another cycle. Two cycles is not something to worry about. If you bought the unit from an Apple store or directly from Apple, it will not be a refurbished MBPr unless they specifically said it was. They don't do things like that.

You should be able to copy all the files from your old computer, although it might not work if the old machine didn't have an intel processor. When I got a new Mac a few months ago, I used the migration assistant to copy everything from my old computer's time machine backup disk. All my old pro apps, such as Final Cut Pro 6, work fine on the new machine under Lion.
Later, I wanted to install Soundtrack pro and couldn't do it from the original disks. So I installed it on my old machine and copied the files. It worked perfectly.

I have a brand new MacBook Pro . I am trying to connect to the private wifi at my house but I need the IP address of my laptop . Everywhere I go on the laptop, the IP address is blank . How do I find the IP address if laptop is not connected to the wifi

I have a brand new MacBook Pro and I'm trying to connect to the private wifi at my house however, I need the IP address. Everywhere I go to find it, the adress is blank. What do I do ?

Your Mac won't have an IP address, at least not a valid IP, until you actually connect it to your home LAN. Not sure why you think you need the IP, you don't.
To connect to your home WiFi you need to know the SSID name, IE the name of your home WiFi, and the password for it. Once you have those two things click the little antenna looking icon on the right side of the menu bar and select your home WiFi name and click connect. A dialog box will pop up asking for the password, type in the password and click OK/Connect/Whatever.

I have a brand new macbook pro 15" with latest Lion.Can anyone tell me why, when I open word or preview etc that multiple files open?For eg if I open a word doc, the last 1-3 docs that I have worked on all open. why?

I have a brand new macbook pro 15" with latest Lion. Can anyone tell me why, when I open word or preview etc that multiple files open?For eg if I open a word doc, the last 1-3 docs that I have worked previously on all open. Can anyone tell me why?

You have a choice as to whether or not applications in Lion like Word or Preview (or even Safari) save and re-open previous documents or windows... just hold down the option key while quitting a program and when you re-open it you won't get the previous documents or windows when you re-open the application. You can see this by selecting the open program in the menu bar and when holding down the option key the quit function will change to quit and discard open windows. This feature in Lion is referred to as "Resume" and is great if you want to restart an app and return to what you're doing (for example in Safari re-opening existing windows and tabs from your previous session). You still have the option to close individual windows within an app before quitting and they will not re-open when the app is launched again.
This Resume function is not related to saving your work (a word or text document for example). This is handled by Lion's "Auto-Save" and "Versions" functions. See http://www.apple.com/ca/macosx/whats-new/auto-save.html
Hopefully this is the complete answer you're looking for.
