For Sale – Mac Mini 2011 i7 FAULTY

My mac mini has developed a fault with (I believe) the dedicated GPU (see photo). It doesn’t get past the boot up screen.

I personally don’t have the time (or inclination) to want to try to fix this.

The spec of this machine is:

  • Mac Mini mid-2011
  • 2.7GHz dual-core Intel Core i7
  • 8GB RAM (2 x 4GB sticks)
  • 500GB hard drive
  • AMD Radeon HD 6630M graphics processor

As far as I can tell, it’s only the GPU that’s causing problems, all the ports, wifi, bluetooth all work.

This is being sold as NOT WORKING and therefore no returns accepted, it might be right for someone who has the time and tools to attempt a fix. Note that as I couldn’t get past the boot screen I have opened this up to get the drive out to recover data and then wipe it.

Please do ask questions if you’re interested.

Wanted – Mac mini or iMac

Looking at a couple of youtube vids it appears you connect the old drive up as a usb drive then boot the mac with a certain key combo to get into a service/disk utility mode then copy the old HD to the SSD from there.

I’ve never done it so you will need to research and be comfortable doing it before you start. I have seen SSD’s for sale with an image of Mac OS on them which could be useful. I believe the OS is downloadable from Apple themselves so you may be able to pre load the ssd. Again I’m not experienced with this so you will need to research yourself.

The Samsung SSD is in use at the moment and the A400 (which is brand new) was earmarked for his PC so not worried if these sell or not as would be replacing at some point anyway. If you want the lot as a package then £275 and i’ll split the postage with you.

Researchers bring back cold boot attacks on modern computers

It’s 2008 all over again as researchers have found a way to leverage cold boot attacks against modern computers to steal sensitive data from lost or stolen devices.

Olle Segerdahl and Pasi Saarinen, security consultants for F-Secure, developed the new cold boot attack method and claim it “will work against nearly all modern computers,” including both Windows and MacOS devices.

In classic cold boot attacks, threat actors could recover data stored in RAM after a computer was improperly shut down, but modern operating systems have mitigations against this by way of overwriting RAM. Segerdahl and Saarinen found a way to disable this feature.

“It takes some extra steps compared to the classic cold boot attack, but it’s effective against all the modern laptops we’ve tested,” Segerdahl said in a written press statement. “And since this type of threat is primarily relevant in scenarios where devices are stolen or illicitly obtained, it’s the kind of thing an attacker will have plenty of time to execute.”

Segerdahl and Saarinen developed a tool that could re-write the mitigation settings in memory, which would disable memory overwriting and allow them to boot from an external device that could read the target system’s memory. The researchers said cold boot attacks like this could be used to steal sensitive data like credentials or even encryption keys held in memory.

“It’s not exactly easy to do, but it’s not a hard enough issue to find and exploit for us to ignore the probability that some attackers have already figured this out,” Segerdahl said in a statement. “It’s not exactly the kind of thing that attackers looking for easy targets will use. But it is the kind of thing that attackers looking for bigger phish, like a bank or large enterprise, will know how to use.”

The researchers said cold boot attacks like this could provide a consistent way for threat actors to steal data because it works across platform. And although the researchers have shared their findings with Microsoft, Intel and Apple, mitigations are still a work in progress.

Apple claims that Macs with the T2 chip are immune to cold boot attacks — though this only includes the iMac Pro and 2018 MacBook Pro models — and suggested users with other Mac devices set a firmware password. Microsoft updated Bitlocker guidance to help users protect sensitive information.

For Sale – Macbook Pro Retina 13, 2015, i5, 8GB, 128GB

I’m possibly looking to switch to a Surface Pro for work, but just weighing up boot camp versus a Windows 10 device.

It’s all boxed, in excellent condition. It was bought from John Lewis as a Xmas present in 2015, I’m not sure on warranty status.

Possibly open for trades (either Surface Pro or Surface Book), but really just testing the water.

Price and currency:680
