VNC connection delay on RasPi 3A+

I've downloaded a fresh Raspbian image and built a system on my lovely new RasPi 3A+. When I try to connect with VNC from my MacBook Pro I get the message: 'The connection was refused by the computer' for about ten minutes, after which the connection is accepted and everything else seems OK.

Secure reformat of memory cards

When you reformat magnetic media 'securely' you write random data across the entire surface, because iron remembers previous magnetisation, leaving slight variations in the magnetisation of the new data, and sufficiently sensitive equipment can decide what was on the medium before the current write....

Re: Printer server problems

Thanks for your reply, epoch1970; I'm sorry to take so lomg to respond, but I seem to have spent a week trying to get something consistent - going back to backups because something has stopped working, mainly. In the end I downloaded the latest Raspbian distro and worked through my change log to reb...

Printer server problems

I'm trying to set up a printer server on a PiZeroW running Stretch, and I'm hitting two problems: 1. The printer is a Brother HL-2035; it's an old printer, but works ok with macOS High Sierra. When I try it connected to the ZeroW it goes through the motions - details in the CUPS web interface, follo...

Re: Installing Homebrew on a Mac

Another try at understanding. You are a Mac user. You want to learn how to use Git on your Mac. The Raspberry Pi Foundation resource you have cited refers in turn to https://www.raspberrypi.org/learning/getting-started-with-git/mac-install/ As you say, that makes the assumption that Ruby is already...

(I'm not sure where to post this; perhaps a kind administrator could move it if necessary.) I want to get Github on my Mac (macOS 12.10.5) but the instructions in the resources section assume I've got Ruby installed. I'm old and cautious, and I don't like getting stuff from random websites, so can y...

Re: Not able to boot raspberry pi 3 using MacBook Air

I've not succeeded in setting a permanent IP address for the RPi, which means I have to root round with IP Scanner to find it. You should be able to connect to your Pi using (for instance) "ssh [email protected]<hostname>.local" where "<hostname>" is the hostname of your Pi. (and it's why I tend to assign unique...

Thanks, but my understanding is that the NOOBS process rewrites the card with the target system, and wipes the original.

Re: Not able to boot raspberry pi 3 using MacBook Air

Assuming you're on a Wifi network: if you enable VNC, and download the RealVNC client for MacOS, you can then remotely access the screen and use the Mac's mouse and keyboard. It can occasionally be a bit slow to respond, but it's the method I use. I also use /boot/config.txt to force the output to H...

Dual-boot a ZeroW?

I adore my PiZeroW, but... I've got the Official PiZero case, and it's really lovely, but I have to take it apart and remove the RPi to get the MicroSD out for a backup. (Unless I've missed something, there's no way to do a backup of the running system.) All this physical handling seems unsatisfacto...

Thanks for that - it got me a step further, but then the boot failed because of a missing file 'applesetos'. Have I got a corrupted distribution, perhaps?

Re: Fixing booting of the x86 image on Macs

I got the red messages as well. It turned out I'd created the enterprise.cfg file in Pages, then saved it as a Pages file instead of exporting to a text file. (You also have to make sure that it hasn't saved it as enterprise.cfg.txt) Correcting that got a bit further, but then the boot process compl...

Can't boot Pixel x86 on a Mac

A long story of failure... I downloaded the Debian/Pixel image from issue 53, burned it to a USB stick (actually an SD Card in a reader, coz my USB stick is stuffed), put it in the slot and restarted my Mac (early 2015 13" MacBook Pro Retina) while I held the C key down. After an age, the Mac apple ...

I'm trying to install gfortran, but the installation reports a dpkg error: "unable to open list file for package 'gvfs-fuse': Input/output error" I've redone "sudo apt-get update" (and "sudo apt-get upgrade" for good measure) and that hasn't helped. Is there a fault in the library, or is it just me?...

I've come on the forum to look for solutions to a problem, which is that the NOOBS downnload fills a 4GB card, and I can't get it to start Raspbian because I need about 200MB more space.
