    My black macbook is red hot when in use as well and when its fans kick in its louder than my Sun SAN on reboot and those that have them know they are noisy!!!!

    Im not in love with my mac really, I use it but its boot-camped so its a Windows 7 laptop more than a Macbook tbh, but I do keep going back to Snowkitty and trying stuff but its sooo different to windows and just seems backwards to me, I spend half my time looking for things and thinking okai on Windows I do x,y and Z to achieve A,B and C and on the mac I just cannot get Y and Z thus fail to achieve B and C

    Maybe one day I will learn to like it more but for now it a great Windows 7 Laptop

    Hi

    "Also is it normal for them to be nuclear hot underneath?"

    Not really. It depends on what you're doing or what you did when initially setting up the laptop. Apart from a mild warmth under roughly the F2-F7 keys and the 2-8 keys that should be it. This is my experience on numerous other laptops I have used. "Nuclear hot" is a slight exaggeration surely? Can you warm a cold cup of tea/coffee if placed on the keypad which would make it hot enough to be drinkable again? Doubtful? If you can there's something seriously wrong somewhere and I'd doubt if you could switch the thing on.

    One thing that regularly ramps up the heat and fan speed is large amounts of data. Spotlight will begin indexing - this also happens upon completion of the set up assistant. The more data there is the more the "mds" daemon works the processor. You could stop this by placing the hard drive into the Privacy section - System Preferences > Spotlight > Privacy.

    Browsing websites with lots of Flash animations can also ramp up the heat/fans especially if a pop up window containing the animation is not dismissed. A lot of Poker sites are guilty of this. Affects Firefox as well so it's not just Safari. As an experiment you could install Windows and see if browsing the same sites in IE causes the same effect.

    In addition to the mds daemon Spotlight uses the "find" utility. If you issue "find /" via the command line and have the Activity Monitor open viewing the CPU Graphs you'll see what I mean as it 'simulates' to some extent what Spotlight does.

    Once indexing has finished you really should see heat values return to more reasonable levels. If it does not you potentially have a problem and I would suggest you take it back to the Retailer or an Authorised Repair Specialist (yes I realise it spells ARS) and get it looked at.

    I agree with AntonioRocco. I've had Macs for the last three years or so and have never had overheating /cut-out issues. If this is happening, I would guess something isn't right.
    Your Macbook Pro may get loud when doing tough numbercrunching but that's to be expected. And I'm pretty sure that the aluminium body is used as a passive heatsink for it, so watch what surfaces you put it on!

    Now, on to some useful things you may not have discovered yet:
    • Enabling tapping and two fingered tapping for secondary click on the trackpad is a very good way of making it feel more comfortable to use.
    • Pressing the spacebar with an item selected in Finder will open QuickView, which can preview most files (.doc, .txt, .pdf, .jpg etc) in a pop-up window without actually opening the associated program.
    • Pressing 'Enter' with an item selected in Finder will allow you to rename it, NOT open it. It took me a while to get used to this.
    • To open a selected file in Finder, press  & the down arrow.
    • You can navigate Finder windows by pressing  & the arrow keys to go up and down folder levels.
    •  & Backspace will delete a file to Trash
    •  & Q will fully Quit an application.
    •  & W will close a window or tab (pretty much any, although some apps like System Preferences will Quit instead).
    •  & T will get you a new Firefox or Safari tab.
    •  & Z will recover an accidentally closed Safari tab (in v5) and , Shift & T will recover an accidentally closed tab in Firefox.
    •  & H hides an application (it still runs, but all it's windows are hidden)
    • , Alt & H hides all other applications except the one you're currently using.
    • , Alt, CTRL & Eject will shutdown your Mac (without a delay)
    • , CTRL & Eject will reboot your Mac (without a delay)


    As HodgeHi said, Spaces is a valuable multi-desktop system I use on my Macs. You can switch between spaces with a keyboard shortcut (normally CTRL & -> or CTRL & <- if you have your spaces set horizontally) or by dragging windows to the screen edge for a second.

    When using options in menus, particularly secondary menus (right-clicks), try pressing the ALT key, as this sometimes offers different options. For example, in a Finder window, the secondary menu contains the option to 'Arrange [your icons] by' size, kind, date etc, but pressing ALT while the menu is open changes this to 'Keep Arranged By'.

    Err, yeah... Hope some of that is of use...!

    Maybe/hopefully things have changed with recent models. But a simple search of popular mac forums/sites will show how common a problem this actually is. I hate to be doom and gloom for an otherwhys outstanding piece of kit but the Magsafe connectors are prone to fraying and the laptop is prone to over heating.

    Hers somesoftware that fixes the problem: Download Fan Control for Mac - Adjusts minimum fan speed on MacBooks. MacUpdate Mac Software Downloads . This software wouldn't exist if Apple didn't purposfully run the fans at a slower rpm and thus cause the problem.

    Also on CD's stuck in the drive (generally caused by aluminium warping - caused by excessive case heat - caused by slow rpm fans): Eject a stuck CD/DVD from a MacBook Pro SuperDrive - Mac OS X Hints

    "This software wouldn't exist if Apple didn't purposfully run the fans at a slower rpm and thus cause the problem"

    I agree and I use Fan Control as result. Something I should have recommended to OP when posting.

    Some PDFs are structured in such a way that the only thing that can read them is Adobe Reader. I get them like that from a few Govt departments and from some suppliers. If I can't see more than a page in quick view I open them in Adobe Reader.

    Any pointers for possible causes? I would prefer to fix the pdfs rather then dealing with adobe hell

    It all boils down to how they were built in the first place. Not much you can do about it if you get one like that. I also get similar problems when trying to open newer PDFs in older version of Adobe Reader. One way around it is to open once in Adobe Reader, go to print it but then use the PDF button to save a copy as a PDF. It usually strips it back to a barebones PDF.

    What version of the pdf specification is the pdf made to?
    I have had this issue in the past; if the pdf is made to conform to a later version of the pdf spec than viewer currently supports then it can't always display it. Kinda makes sense as there might be features in the pdf that viewer doesn't know what to do with.

    I thought the idea of owning a mac was it 'it just works' - clearly this is not the case.........

    The same docs that have problems in preview are an issue in other PDFs readers such as FOXIT and Okular ... I blame Adobe for hating Apple.

    Here are some useful keyboard shortcuts:

    Log out: shift, command, Q (or shift, option, command, Q to omit the "are you sure?" message)

    In Safari, if you have a bunch of tabs open:
    Shift, command, [ gives you the previous tab
    Shift, command, ] gives you the next tab
