Several times a day I get a box saying "another user is trying to access your computer"I then get the option of agreeing or cancelling.Obviously I deny access but what can I do to prevent it from happening?
Pour coke down the back and claim on the insurance... Alternatively, is there any other information on the pop-up box? - does it indicate what program is detecting it. I would recommend updating your AV software and running Malwarebytes to detect anything nasty on your computer then see about installing a firewall.
What do you want to stop happening, the box appearing or people attempting to access your computer? If it's the latter, then they're not really. Well, they are, but they're not targeting you specifically. Well, I doubt they are, maybe you're a spy in which case they probably are. But supposing you're not, what is actually happening is that hackers have software that attempts to find vulnerabilities in thousands of random computers at once. Every day every computer is hit by thousands of these, but even the most basic firewall fends it off. It's not a serious attack on your machine. If you want the box to stop appearing, it would be useful to know which piece of software is giving you these warnings. It's either a legitimate piece of firewall/anti-spyware/anti-virus software that you have installed or some spyware/adware trying to get you to install something of theirs. Either way, the box should identify which software it is. If it's a legitimate piece of your software then there will be a way of turning off these notifications. It'll carry on doing what it's supposed to be doing, it'll just not tell you about it all the time. If it's some malware you'll have to either uninstall it or use some software to do that for you. Can't help you more than that without you identifying which program is giving you these messages.
once spent the best part of two days trying to get a mac to detect a wireless printer, i eventually called kodak (who made the printer) and they said, "we've been suggesting that mac users use the included USB cable to connect to the printer"...f**king joke, not necessarily Apple's fault, but one of the many sacrifice's one has to endure if you want to do anything outside of what comes included with the OS or in an Apple box. This is the reason the Macs are much more stable, if the same restrictions applied to Windows machines it would be just as stable. Saying that, I haven't really had any reliability issues with Windows for years, and although I don't like the changes made for Windows 8 you can't grumble at how it performs, the fluidity is definitely on a par with a mac, which is impressive given that you could plug a Breville Sandwich Toaster into a Windows PC and it would try it's best to give you some options for controlling it.
My ex-girlfriend was (and I assume still is) a massive fan of Apple, she didn't drink or smoke so could pretty much afford whatever she fancied - which was pretty much everything Apple sold at the time so I've had a good play with all their kit and I have been an iPhone and iPad user for the last couple of years, but OSX is f**king w@nk...it has merely become the defacto platform for design agencies (you know the type of place where they hi-five each other every morning and have a basketball hoop on the wall?) yet the software they run (mainly Adobe Creative Suite) is exactly the same on both Mac and PC except the CPUs available for PCs are always a generation ahead of Macs so in reality you would actually get more done on a PC as you'd be able to render images and video much faster.
