mac – iPhone charging from MacBook Air 2017

I have an issue when I plug in my iPhone 11 Pro Max into my MacBook Air 2017. The issue is that it starts to charge for like 1 second, disconnects for 5 seconds, and then loops like that. Do you think the issue could be with the port or the software?

I am running macOS Catalina 10.15.5 and iOS 13.6.

restore – Can a transaction log backup create a new database before any full database backup is applied? SQL Server 2017

We have a large database we restore daily from a single t-log backup from a remote supplier. We are looking to move to 15 minute t-logs, but applying these to the current database on prem it is then very hard to see just what has changed, to update the downstream warehouse tables. A hypothetical solution would be if it were possible to take a t-log as it came in, restore it to a new database, and then be able to compare tables in that with the tables in the full database to then create some sort of UNION view that reflects the current state.

But I am 99.9% sure you cannot restore a t-log if you have not restored a full backup before, hence I am looking at ApexSQL Log to read the t-logs instead.

But if I’m wrong, please let me know! I’d love to be able to restore a single t-log to a new database!

sql server 2017 – Backup Restore, CPU usage and Extended Events

I’m working on measuring the performance impact of Backups on CPU. I would like to capture all the backup operations and CPU usage. I’m running a weekly full backup, daily diff, and 15 min log backup. Are there any options in Extended Events we can use to capture CPU usage?

CREATE EVENT SESSION (Backup_Events_Trace) ON SERVER ADD EVENT sqlserver.backup_restore_progress_trace (ACTION(sqlserver.client_hostname, sqlserver.database_name))
    ,ADD EVENT sqlserver.databases_backup_restore_throughput (ACTION(sqlserver.client_hostname, sqlserver.database_name)) ADD TARGET package0.event_file (SET filename = N'L:XEBackup_Events_Trace.xel')

macos – Why did my 2017 12” MB go into kernel panic (page fault)?

I was just browsing using safari, had word, notes, chrome and maybe some other light apps open in the background but nothing heavy. Suddenly my mac shutdown and restarted with the “restarted because of a problem” message. I’ve definitely put this macbook into much more stress so I’m lost. It’s a two year old 12 inch Macbook. I just booted pressing D and the report says No problems were found, code ADP0000.

The crash report is as follows; I don't know how to interpret it. I’m really worried.

Error while upgrading SQL server 2012 to SQL 2017 : Failed to create a new folder ‘X:\xxxx’. The specified path is invalid

Failed to create a new folder ‘X:MSSQLDATAMSSQL11.MSSQLSERVERMSSQLLOG’. The specified path is invalid (for example, it is on an unmapped drive).

I checked there is no X drive present in the server. I verified that all the default files for data and log points to the drives which are available in the server.

Not sure , how do I resolve this as i don’t see X drive mentioned in any of the properties.

I have checked in Facets and database properties to verify the path.

SQL Server 2017 SSIS Package Export failure

Upgrading from SQL Server 2008 R2 to SQL Server 2017. Using SQL Server Business Intelligence Development Studio. I am able to publish to one SQL Server 2017, but fail to publish to another SQL Server 2017 with error “An OLE DB error 0x80004005 (Client unable to establish connection) ocurred while enumerating packages. A SQL statement was issued and failed.” I have compared server settings and permissions without success. I must be missing something…

Link Displays Between Two iMacs (Late-2015 Retina running Sierra and 2017 running Mojave) Using Thunderbolt-to-Thunderbolt

I’m hoping someone can help me (and that this is possible, considering I just spent an arm and a leg to facilitate this setup).

I have a late-2015 iMac (27″ Retina 5K display, running Sierra) and a 2017 iMac (21.5″, running Mojave) and am hoping that I can connect them for dual display. I have them connected via Thunderbolt-to-Thunderbolt with the TB2 to TB3 adapter. For whatever reason, I’m not able to use Target Display mode on my 2015 iMac, and I’m suspecting it’s because the model doesn’t support it. ETA: The other mac doesn’t show up in either System Preferences > Displays menu

I’m hoping someone can offer advice as to what I’m doing wrong or a possible workaround for this issue, as I have no use for both iMacs separately but would greatly benefit from using one as an additional display – even if the answer is simply that I can’t do it, it will at least allow me to stop spinning my wheels and give up on this pipe dream.

Any suggestions are welcome!
