Dual booting Kali on Mac, Mac doesn’t load EFI bootloader

I resized my Macs SDD to have 45 GB of MS-DOS FAT, I burned the kali .iso to my USB and installed Kali on the 45GB Free space where I set it as ext4 and /(root) filesystem.

However I skipped the GRUB bootloader as I read it won’t be able to recognize your OSX, leaving you only with Kali linux (ofcourse this can be solved, but I’m not sure if I have working Wifi on the Linux).

Now this is my problem, when I reboot, it will reboot into OSX, when I hold alt, it only shows OSX even though I put KL on the 45 GB free space.

How can I make it so that I can boot with rEFInd into Kali(and OSX)?

My diskutil list

disk0s1 is obviously listed as EFI. When I try this it says:

sudo diskutil mountdisk /dev/disk0s1 One or more volume(s) failed to mount 

Preseeding Dual boot dual hard drives Ubuntu 18.04.1 LTS

First post here. Just wondering if anyone can help. I’m not Linux expert or anything so this may just be my brain frazzling!

Ok, so I’m using the same hardware and same method I have been using with 16.04.x which all worked fine. I am using a fairly new pc with two nvme hard drives in (one 500gb and one 250gb). In my preseed file under partitioning I specify the 250gb disk (d-i partman-auto/disk string /dev/nvme1n1) for Ubuntu as Windows goes on nvme0n1 (the 500gb disk). My auto deployment/installation of Ubuntu works fine for a few times but then suddenly i’ll find that for some reason its installed itself onto the 500gb disk instead of the 250gb?! If i then look in gparted or do lsblk the disk labels have swapped over so now the 250gb disk appears as nvme0n1 instead of nvme1n1 and the 500gb appears as nvme1n1 instead of nvme0n1. If I reboot then usually the labels have switched back to how they should be but obviously Ubuntu has now written over the windows 500gb disk. When i deploy Windows 10 via sccm it will consistently deploy to the 500gb disk (disk 0) Any suggestions or workarounds would be greatly appreciated. Currently i’ve sort of given up on this and am waiting for 18.04.2 to see if that fixes anything. Thanks Rob

I’m a flight attendant with dual citizenship of USA and South Korea. Can I enter US using foreign passport?

If I want to use my staff ticket I have to book the ticket under my Korean name (which is completely different from my English name) and Korean passport number. The only thing is I know that for the US you have to enter and leave using your US passport if you’re a citizen. Would it be possible for me to just buy my ticket using my Korean name and passport but when I enter the US just explain my situation and show my US passport to show that I’m a US citizen?

Kde: dual monitor when primary monitor is a touchscreen: calibration

I just moved from gnome to kde and have loved it, but one thing is causing me trouble. I am a teacher and regularly connect my laptop to many classroom screens as well as my external monitor at home. My laptop has a touchscreen that also includes a pen and stylus. I use the pen and stylus regularly on the touchscreen.

On moving to kde, however, the pen no longer automatically calibrates properly, and moves around some distance away or even on the external monitor when I touch my laptop screen either with my finger or the pen.

There have been suggested manual solutions to this, but I am switching screens all the time. Is it possible for kde to be set up to automatically configure a range of monitors and inputs correctly, as gnome and unity already do?

Not receiving notifications on dual WhatsApp on Samsung Note8

I have two instances of WhatsApp on my Note8. When I receive a message on my primary WhatsApp, I get notifications instantly as normal. However, on my dual WhatsApp, I don’t get notifications unless I open the app.

Sometimes, I get notifications come in all of a sudden as if the app has come alive and checked, but this is not consistent with the primary app.

I’ve gone to Settings->Notifications and there is only one ‘WhatsApp’ app listed and notifications are enabled. However, this cannot be where the issue is as the notifications are fine for the primary app, just not the dual app.

If I go to Settings->Apps, then here I do see both instances listed. And notifications are enabled for both. I’ve also checked the Mobile data settings for both, and they both have Allow background data usage enabled. I am not using Data saver.

The only thing I’ve not tried is disabling Optimise battery usage for WhatsApp as this seems to be for both instances of the app, not either. But other than that possibility, I’m stumped. Any ideas welcomed.
